Thanks blas!, but i would like to use the prestressed normal modes in a frequency response analysis. I've got prestressed normal modes in the normal mode solution but i don't know how to introduce this normal normal modes in a frequency response. Thanks for all! Regards.

Hello everybody! Does anyone knows the way to use prestressed normal modes in new analysis (frequency response sol 111)? Thanks in advance, regards!

Hi pals! I want to know how i can do a topography optimization using patran. Does anyone know where i can found information about it? (Examples step by step) I've found examples for dimensional and topology optimization, but i can't found for topography. Thanks in advance

Hi pals! I want to know how i can do a topography optimization using patran/nastran programs. Does anyone know where i can found information about it? (Examples step by step) I've found examples for dimensional and topology optimization, but i can't found for topography. Thanks in advance!

Thanks a lot dwallace1971!! Using diferent analysis by group i can do all the combinations of elements that i want. Thank you so much!

I'm using Patran 2012

Hi pals! Does anyone know if its possible to deactive elements for an specified analysis and active for the others? I want to do all the analysis with only one .db. Thanks in advance! Regards David

Hi Pals! I would like to know the values of element quality criteria in IDEAS, and the relationship with the values in Patran. I've followed the patran restrictions in my model but i need to know the minimum values in IDEAS to obtain a good mesh. Thanks!

Hi pals! Does anyone know how to extract mid-surface from Solids? Thanks in advance! David

Dear Blas; First of all, I've to tell that I created the model in Patran. Then I imported it in FEMAP because I read in some forums that is a useful way to translate to ANSYS. When I export the model to ANSYS, femap ask me what kind of translation want to do: CP coupling constraint...

Thanks Blas! It works fine! One more question; When I do the translation, the RBE-3 (that are include in the model) have a mass associated that I didn't create. What is the reason for this behaviour and how can I resolve the problem?

Hi pals! Does anyone knows how I can export femap model to ansys? I've tried to use the Export model icon but doesnt work. Thanks!

Hi all! I've found useful information about superelements in www.6dof.com, but at Split database Examples I can't open the .dat files where the examples are placed...

thread727-224740 Hi! I can't open the .dat files located in Topics of Superelement analysis in MSC/NASTRAN - Split database Examples (referent to this thread). Can you help me, please? thanks!! regards
