Creo Simulate FEM Mode Structural:Export user defined material properties to FEM Neutral File/.fnf

The export of Creo Simulate model into the FEM Neutral File includes only 13 predefined material properties like YOUNG_MODULUS, POISSON_RATIO, .. etc. The export of user defined material properties is excluded from export to FNF-file. This malfunction disables proper use of user defined solvers, which require additional material properties.

We propose in this idea/enhancement to include the user defined material properties into the fnf output. The current fnf format can be used, for example:

%MATERIAL 1 YOUNG_MODULUS : 1
%MATERIAL 1 POISSON_RATIO : 0.3
%MATERIAL 1 USER_DEFINED_NAME_ONE: 1.2
%MATERIAL 1 USER_DEFINED_NAME_TWO: 5

%MATERIAL 1 USER_DEFINED_NAME_THREE: abc

%MATERIAL 1 USER_DEFINED_NAME_FOUR: yes

This allows to handle all data types of the user defined material properties: Real_Number, Integer, String, Yes_No  (the real number is the most important).

 

Optionally, the export to fnf-file can be controlled by a config option e.g. fem_export_user_properties no*/yes. This would allow to preserve export format for old models.

 

This Idea/Enhancement is very important for management of CreO models in PDM. Without this feature maintenance of simulation models integrated with CreO is disabled in our company.

 

We have submitted tis idea on recommendation of PTC Support after consultation with CreO Simulate developers. The corresponding case is 15603739.
