I want to model an Al honeycomb in 3D Properties.
I could use Shell to create a hexagon, but I am looking for a different method because it is difficult to model and computationally expensive.
Is there a better method to make a model with…
When attaching the xdb file in Patran, I get " $# *** Begin: Attach Result File *** "
The same code gives me results if I ask for a op2 file and there are no fatal errors in the f06 file.
What could cause this?
Thanks for you hel…
I am analyzing a satellite in Geostationary Transfer Orbit (GTO).
I would like to do a thermal analysis in GTO, is there any way to simulate it?
I would like to achieve this using Partan.
Should I ask this question on the Nastran forums…
Hello i have rubber model of silentblock using sol400, my first load step is static, where is defined initial temperature 150 degs and nodal temperature at time 1 (20 degs). From disp. results it looks like model is working (silentblock is shrinking)…
Hello
I have a model that I am checking for any errors. I ran a free-free modal analysis. Instead of getting 6 rigid body modes (zero), I am getting the first 3 modes as 0 while, the other 3 (rotational) are not perfectly zero. It has a value of…
Hi, I have a bdf which was created with Patran 2014, but my university has Patran 2016, and everytime I try to import it I get the error Creating Nastran Database using SOL nifimp_v22: Failed but continue. I feel the old formatting of the bdf is not letting…
According to the QRG, the Shear Stiffness Factor K adjust the effective transvers shear cross section area according to the Timoshenko beam theory.
But how do I compute this value for my beam?
I cannot use the Patran Beam library because my…
Dear all,
I have a big assembly and want to model bolts in the complete assembly. What is the best and accurate way to model this.
Cbar analysis is accurate enough to analyse the bolt forces. Boltstress is of secundair interest.
Are there…
Dear all,
I would like to study some examples with linear gap elements. We don`t have SOL400 available and to have a work around for i.e. objects touching or near eachother.
Could you provide wtih some examples or give location of study material…
