The new release version of the PrePoMax contains the following FEM features:

  • added support for amplitudes by radiation emissivity and film coefficient
  • added support for splitting periodic CAD surfaces (periodic surfaces with only one edge, like cylinders) during CAD file import: Tools → Settings → General → Import CAD
  • added support for parameters to all initial conditions
  • added support for imported ST load
  • added support for initial angular velocity

and the following user features:

  • added support for execution times of history commands
  • added region field in all mesh setup items
  • added support for displaying symbols for initial conditions
  • added support for highlighting items in trees and list-views on mouse move

The previous initial velocity item was wrongly defined based on elements. I had to change this to be in accordance with the CalculiX definition, which is based on nodes.

That is why PrePoMax will NOT open any older version files containing initial velocity. A simple fix is to delete the initial velocity from the old file using an older PrePoMax and recreate it in the new version.

The imported surface traction load can be read from a txt file containing the following data structure:
#X Y Z Fx Fy Fz
0 0 0 1 0 0
…

The # stands for a comment, the X, Y and Z are coordinates of a point with a surface force with Fx, Fy and Fz components and a unit of [force/area].

@Matej, Could you please elaborate on this user feature ? I don’t quite follow.

If you move the mouse over the model tree the item under the mouse is shown in light blue color and the item is highlighted in the 3D view.

Hello, could we import nodal temperatures as defined fields from an .inp file just like in Calculix?

i’m still waiting PrePoMax support initial condition type stress based on part, could be useful to define bolt prestressed and initial residual stress. Thank you.

Temperatures can be imported as in CalculiX but not from an .inp file but from the .frd file. Use defined filed for that:
