Suspension Dynamics Calculator
OK, here is the motherload.
This is a web-based version (slightly simplified) of the Excel spreadsheet I designed and used to work out all the various calculations needed to properly set up the car.
- Online vector calculator - add vectors with different magnitude and direction - like forces, velocities and more Vehicle - Distance Traveled vs. Velocity and Time (km/h) Speed (km per hour), time (hours) and distance traveled (km).
- Math Dynamics is an instrument that you can add to your tool chest that gives you an edge when it comes to everyday activities that demand a quick calculation. Calculations can range from simple arithmetic to multivariate formulas like Cost per Unit, Miles per Gallon, etc.
- Dynamics Calculators comprises a selection of 5 different calculators that will simplify calculations which have given you headaches so far. Complex calculations, such as Oscillation Period of Double Pendulum, Mach Wedge Angle for Shock Waves and others listed below will be handled easily with this app.
Yes, the graphs don't work in Internet Explorer (download Firefox already, all four of you who still use IE!)
The remaining work on it is to provide a data entry block for your own shocks (to compare against the theoretical ideal)
Fire Dynamics Simulator Mesh Size Calculator t-squared Fire Ramp Calculator. Online tool to calculate a t-squared (time squared, or t 2) heat release rate curve, which is commonly used to estimate transient fire growth for fire protection design purposes. T-squared Fire Ramp Calculator. Dynamics Calculator is an easy to use App that Contains 78 Dynamics Calculators Split into 3 Categories: Basic Dynamics Includes 5 Calculators: - Young Modulus of Isotropic Elastic Solids - Terminal Velocity - Impedance of Forced Oscillation - Oscillation Period of Double Pendulum - Mach Wedge Angle for Shock Waves Astrodynamics 24 Calculators.
The key to using this application is Accurate Measurement. There's a lot of data you have to pull off the car and accuracy counts!
Remember: Garbage In, Garbage Out!
Some of the data is fairly simple to collect (like corner weights). Others, (like CG height and roll centre height) take a little more work.

Please read our article updated in 2020 here.
In Microsoft Dynamics CRM 2015, Calculated Fields and Rollup Fields are new field types making it much easier to automate calculations and special processes – which previously might have required manual calculations or JavaScript – without writing a single line of code! Just add a new field to your entity, define your criteria and logic (like setting up a business rule), add the field to your form and watch the magic happen! Okay, there might be a couple more steps to it than that, but Microsoft has made it a fairly straightforward process.
In this article, we’ll focus on Calculated Fields. To learn more about Rollup Fields, please see our blog, How to Create Rollup Fields in Microsoft Dynamics 365 (CRM).
Below is a look at all the new things you can do with calculated fields and, as you can see, they allow you to do a lot more than standard mathematical calculations like you might think.
Available Calculated Field Functions
Function Syntax | Data types | Description | Return type |
ADDDAYS | whole number, date and time | Returns a new date and time that is equal to the given date and time, plus the specified number of days. | Date and Time |
ADDHOURS | whole number, date and time | Returns a new date and time that is equal to the given date and time, plus the specified number of hours. | Date and Time |
ADDMONTHS | whole number, date and time | Returns a new date and time that is equal to the given date and time, plus the specified number of months. | Date and Time |
ADDWEEKS | whole number, date and time | Returns a new date and time that is equal to the given date and time, plus the specified number of weeks. | Date and Time |
ADDYEARS | whole number, date and time | Returns a new date and time that is equal to the given date and time, plus the specified number of years. | Date and Time |
SUBTRACTDAYS | whole number, date and time | Returns a new date and time that is equal to the given date and time, minus the specified number of days. | Date and Time |
SUBTRACTHOURS | whole number, date and time | Returns a new date and time that is equal to the given date and time, minus the specified number of hours. | Date and Time |
SUBTRACTMONTHS | whole number, date and time | Returns a new date and time that is equal to the given date and time, minus the specified number of months. | Date and Time |
SUBTRACTWEEKS | whole number, date and time | Returns a new date and time that is equal to the given date and time, minus the specified number of weeks. | Date and Time |
SUBTRACTYEARS | whole number, date and time | Returns a new date and time that is equal to the given date and time, minus the specified number of years. | Date and Time |
CONCAT | single line of text, single line of text, … single line of text | Returns a string that is the result of concatenating two or more strings. | String |
TRIMLEFT | single line of text, whole number | Returns a string that contains a copy of a specified string without the first N-characters. | String |
TRIMRIGHT | single line of text, whole number | Returns a string that contains a copy of a specified string without the last N-characters. | String |
At the time of writing this article, some additional calculated field functions have been added as part of the Spring 2015 Update, but these are currently only available in CRM 2015 Online, not on-premise.
DIFFINDAYS | date and time, date and time | Returns the difference in days between two Date and Time fields. If both dates and times fall on the same day, the difference is zero. | Whole Number |
DIFFINHOURS | date and time, date and time | Returns the difference in hours between two Date and Time fields. | Whole Number |
DIFFINMINUTES | date and time, date and time | Returns the difference in minutes between two Date and Time fields. | Whole Number |
DIFFINMONTHS | date and time, date and time | Returns the difference in months between two Date and Time fields. If both dates and times fall on the same month, the difference is zero. | Whole Number |
DIFFINWEEKS | date and time, date and time | Returns the difference in weeks between two Date and Time fields. If both dates and times fall on the same week, the difference is zero. | Whole Number |
DIFFINYEARS | date and time, date and time | Returns the difference in years between two Date and Time fields. If both dates and times fall on the same year, the difference is zero. | Whole Number |
Let’s walk through creating a calculated field for a fairly simple requirement. We want to track annual membership dates and we would like to be able to enter a Membership Start Date and have the system automatically add one year to this date to give us the Membership Expiration Date. We already have a field for the start date but we need to create a new calculated field for our expiration date.
How to Create a Calculated Field in Dynamics CRM 2015
1. Create a new field in your entity and in Field Type select Calculated.
You will see an Edit button appear, but IMPORTANT notes before you click on Edit to build your logic.
- Be sure to choose your field Behavior (if applicable) and Format before clicking on Edit because once you click on Edit, you can’t come back and change these.
- All DIFF functions require that the first Date and Time field and the second Date and Time field have the same behavior: User Local, Date Only or Time-Zone Independent. If the behavior of the second field doesn’t match the behavior of the first field, the error message is shown, indicating that the second field can’t be used in the current function
2. Click on Edit to setup your functions and logic for your calculated field.
Our logic here is if the Membership Start Date contains data, we want to add one year to that date and populate our Membership Expiration Date calculated field.
3. First, select the Condition for your calculated field and click the checkmark to save it.
4. Next, select the Action for your calculated field. We selected the ADDYEARS function. When you select it, it appears with a set of parentheses () next to your function name. Between these parentheses is where you define your action. In this case, we entered (1, new_membershipstartdate) as the two components to our action:
- We enter a “1” because we want to add ONE year to our first date field
- We enter (or select from the drop down list) “new_membershipstartdate” because we want to add one year to our Membership Start Date field. Note the schema name of your field is what you will see in the drop down list, but your final action will show your field label.
5. Click the checkmark to save your action and you can see our complete criteria for our new calculated field.
6. Click Save and Close and then be sure to Save your new field setup in your solution.
7. You’re ready to add your new calculated field to your form and test it.
We entered a date into the Membership Start Date and when the change was saved to the record, our new calculated field automatically added one year and populated our Membership Expiration Date.
Special Considerations
Calculated fields are an exciting addition Microsoft Dynamics CRM; however, there are some limitations and things to consider. I’ve listed a few here and you can view more details and examples of calculated fields on Microsoft’s page here.
Molecular Dynamics Calculations
- Calculated fields are read-only.
- A calculated field can span two entities (current entity + parent record).
- You can’t trigger workflows or plugins on calculated fields.
- To create a calculated fields, you must have the Write privilege on the Field Security Profile entity.
- A maximum number of chained calculated fields is 5.
- A calculated field can’t refer to itself or have cyclic chains.
