Who can guide me through a Fourier Transformation in Patran/Nastran? To run a modal transient analysis I need to know which modes are dominantly participating.
Thank you.
I am doing an impact simulation on an electronic housing. The material is an injection molding ASA grade with enhanced toughness and heat resistance.
Any recommendations regarding material properties required for this analysis?
Additional to the usual, Young’s Modulus, Poisson’s Ratio...
Hi all,
I recently read in the MSC.Dytran users guide:
Euler with shear strength used to model
- Solids with large deformation
- Viscous fluids
- Viscous gases
Ok, a gas can exert a tangential (shearing) force on a surface, which acts like friction between solid surfaces. This "sticky"...
Hi all,
Can someone explain to me why ones would build a finite element solid model with a shell skin? Is it for more accurate answers on the surface? How does one determine the shell thickness to get the most accurate answer bearing in mind not to add too much material or additional stiffness...
I recently had a NASTRAN model with CQUAD8 shell elements. The model was perfectly correct, but I still got the FATAL MESSAGE 9050. I then changed the CQUAD8 to CQUAD4 and the model ran through. A possible explanation for this as follows:
... boundary consists of p-element edges along an...
