Thank You very much:).

Hello to everyone I participate ESEO project. I task is carbon fiber mounting of antena. I did analysis to cover requirements, but i got a problem with SRS analysis. For FEM calculations I use NX, where I can find maximum ply failure for random events, but I need Power Spectral Density curve...

Hello everyone. I got a problem with meshing 2d frame model. There are several weldings. I allways stiched edges in weld edge, but this time I got realy problems. Welded edges between tubes i solved by addig there fillets, but i still have problem with some mountigs. The problem looks that...

Now it's clear:) Thank you very much for comprehensive reply. Regards m Wnuk

Thank you very much! I checked for 1.3e7 but it started works from 1e8:). Could you tell me what this parameter do to solver? regards

As an actual sentence if anyone would read this, there is no problem with flat geometry to calculate witch 2nd order elements laminates. Any ideas?

Hello, I did few analysis for laminates in nx with nx nastran, but when I tried to changed element type to CQUAD8 it allways gives me error in f06 file connected to unconstrained mechanism. setting param bailout to -1 make that results are there, but I think it is not a correct solution for that...

I'm running NX 8. I need this geometry to simulate a behavior of aluminium insert in sandwich material (cfrp + al honeycomb), with the potting material around insert. In simulation module there is no problem with that geometry to stich all with even automatic stiching, but i got a problem with...

This is my first topic on Eng-Tips, so hello to anyone. I've got a problem with modeling a honeycomb. I did one cell of honeycomb panel with some faces - which I need to have no double faces, when use pattern, and here everything is ok. The problem starts with sewing all cells together. I...
