Re: Meshing a CubeSAT model+Lengthy post processing times

The factor you use when importing a Parasolid file only affect to the geometry: if you use 1000 it means that the geometry will be scaled in FEMAP to be in milimeters, but nothing to be with units loads, this is up to you: you need to be coherent between the units of material properties and the load units. If EX is defined in MPa, then loads should be in N and length in mm, etc.., understood?.

Go to the <Tools><Measure> set of commands and check your geometry.   If it is in mm and that is how you want to continue then use the METRIC set of units from Chip's table (mm - N - tonnes - deg C). You also need to make sure your materials are defined in the same set of consistent units as the geometry being imported.  if you are using mm then the appropriate material library to use is mat_eng_mm-N-tonne-degC-mW.esp.  To access it click the <Choose Library...> button when selecting a material.  If you use materials with the wrong units then normal modes / frequency response analyses will give wrong answers.

Yes, Understood. Thank you very much

Thanks for this, I selected the library as you advised, by buckling analysis checks out.

 

Thank you.

Also, normal modes and frequency response checks out. Thanks for the help.
