Linear Buckling Analysis - buckling modes
Hello, I am performing a Linear Buckling Analysis in Optistruct. On one end of my rod I have created my Constraint and on the other one my load, a force. As I change the magnitute of the force I am getting different results for the buckling modes. The eigenvalues change in such a way that I would get different critical…

Explanation of the weighting factor of a RBE3 element
Hello everybody, I am relatively new in Hypermesh. Can somebody explain me what is the meaning of the weighting factor of a RBE3 element, what does it mean 1, what does it mean when the value is 0,5 or 1,5. Changing it´s value what does it mean. And the value, what does it mean, is it distance dependent, etc.? What does it…

How to calculate the average displacement of a component in OptiStruct?
Hello everybody, I do a Modal Frequency Response Analysis on a component. As a Output I receive the displacement at all nodes of the component. Is there any possibility in OptiStruct to directly calculate the average displacement (spatial average over all nodes)? At the moment I need a MatLab script for post-processing,…

Creo geometry import creating assemblies for almost every part
Whenever I import an assembly Hypermesh is creating an assembly for almost every part. The actually assemblies still work, but having 110 "assemblies" where there are only a handful makes locating the proper ones difficult. The assembly hierarchy is also not tabbed, so without clicking them you cannot see what the…

Question about Maximal relative permeability
Hello, can you please assist me with the maximal relative permeability ? I'm not sure which value to use, i used the value someone send me on the forum here. For the Remanent flux density and the coercive field strength i used the values from the datasheet of vacomax, i attached the pdf document. Any advice? Best regards

Tcl's not running in batch mode
Hello, all, I have a Tcl script that is working very well on the HyperMesh interface (I've tried in the command window and as File>Run> Tcl/Tk script too), but when I run using batch mode, something happen that stops the looping job. Even the 'command.tcl' stops to write in a random built-in command. As general, the .bat…

Reading the reaction force from the independent node for an RBE2 / RBODY element
Hi, I want to rotate a simple geometry around the axis passing through the center of gravity and calculate the required moment. I also compare the value I calculate analytically with the value I calculate numerically. For this, I used x and y elements and read the moments of reaction from the independent node of these…

Hypermesh Scripting - how to carry out boolean operations on groups of type SURFACE_ELEMENT (abaqus).
Hi, I am seeking a method to generate new element face based surface definitions using Boolean operations where the element faces being operated on may come from either already defined groups (ABAQUS interface, card type SURFACE_ELEMENT) or the special group "^faces". There are two issues: First: I have not found a method…
