Surface IDs keep changing
Hi all, I am trying to automate fillet nodes detection and splitting the surface as shown in the figure. The code will detect nearest node as you can see in the command window (in fig) and split the surface. The PROBLEM is that surface IDs keep changing after every split and the code is throwing error. Can anyone help me…

How to start a static analysis with element density data?
Hello, I am working on density-based method topology optimization. The compliance optimization is defined as: * find X = [x_1, x_2, ... ]^T * min u^T * K(X) * u * such that K(X)*u = F and sum of all x_j * dV - V <=0 * (X: element density, u: displacement vector, K: global stiffness matrix, F: external force vector, V:…

Can I use Hypermesh to export mesh for Comsol's ACDC module which is for electromagnetics?
Hi all, Recently I need to use Comsol to do some electromagnetic analysis. But I need to mesh outside Comsol use Hypermesh. Does anybody know whether the Hypermesh can output matching mesh types to Comsol?

Can some share the document for supplement creation with modal analysis and superlement generation step
Hi , I am new to optistruct, may I know how to create superlement in Opti struct( none of the previous questionnaire links inside Altair community are working for me !). i have attached a file which is imported from abaqus for the same steps and want to replicate same in Opti struct. Thanks.

RBE3 in combination with ADMAS and GRAV
Dear all, I made a small test model in to check the load distribution in an RBE3 element in Radioss. The model consists of a square tube (2D shell) and an ADMAS (100 kg) which is connected to all nodes of the top side of the tube using an RBE3 element. Weighing factor is 1 for all master nodes of the RBE3. ADMAS is exactly…

When applying a pressure load, is the magnitude value the total amount of force applied or the force to be applied to each element?
I am working on a university project. I need to apply a total load of 6kN across a seat belt uniformly. To do this I was using the pressure function. For the magnitude, do I input 6kN? Or do I need to calculate the number of elements and enter 6kN/#elements? I am not sure if the magnitude is the total force or the force to…
