A new developer/preview PrePoMax version v2.1.2 has been released

A new developer/preview version of the PrePoMax contains the following FEM features:

  • added support for the creation of the field output defined by the equation (Result → Field Output → Create)
  • added support for the creation of the history output defined by the equation (Result → History Output → Create)
  • added support for filters for the user-created history outputs; possible filters are min, max, sum, and average
  • coordinate system bug fixes

The filters can be used in pairs since a single filter takes in the history output, which is, in general, a matrix (time versus the selected node values) and returns a row or a column.

For example, suppose the maximum filter is selected, and the return type is column. In that case, the filter will look for the largest value in the history output matrix and return the column where this maximum value is located. This way, the entire time history for the node where the maximum value is determined is reported.

Sorry but I’m failing when using “the power of” in equations by using the operator “^”. It shows strange behaviour (or am i using it wrong?)

Some examples

For equation solving a library Ncalc is used, which supports the following functions Ncalc - Functions | ncalc Tutorial. So in order to have a power operator one must use =Pow(value, exponent)

The ^ operator is considered a C# logical operator: Operators and expressions - List all operators and expression - C# reference | Microsoft Learn

Looking at the documentation, there is no easy way to change the default behavior of the ^ operator.
