I recently learned how to generate a metrics report out of simulation, using dcreport. I'm collecting some functional coverage, with some covergroups with coverpoints and crosses. I opened the generated XML and clicked on one of the covergroups: The report only shows the percentage of hits, but not details about what is…

Description: I am trying to do hex meshing for CFD in Hypermesh. I want to import a .step or .igs file and create hex mesh and then export it to a .msh or other mesh formats. I could import the .step file but I am unable to do the named selection or name of the boundaries (inlet, outlet etc). Will just hypermesh work in…
Hello, I’m having a small issue with composite optimization. I need different thickness constraints on my part during FreeSize and Size optimization. The HyperMesh help site mentions that it’s possible to assign multiple LAMTHK constraints to one DSIZE card, but I can’t figure out how to do it since there is only one field…
let's suppose a non-coaxial cable where the inner conductor is shifted from the main axis of the outer conductor. does there is a way to extract the transfer impedance of this cable by using the full-wave simulation ? suppose the shield is braided as shown in the image. However, the inner conductor is shifted (in the image…
Dear, I am strugling to post process the contact results of analysis with CGAP elements in Hyperview. My main focus now is post processing, but please it would be helpful if someone could also share with me some documentation about the usage of CGAPs in linear and non-linear analysis. Training material (hands on tutorials)…

On a PCBA board, we’re running a solder fatigue calculation using the Blattau method on a BGA component, but the solver is not detecting the PCB–Solder and Solder–Package interfaces. Note: the exact same model works with the Syed method (same PCB/balls/package sets, and the same TIE contacts PCB/Solder and Package/Solder).…
Hi everyone, I am currently working on a motor design project and have successfully completed the 2D Electromagnetic Analysis in SimLab. My goal is to perform a Transient Thermal Analysis while keeping the workflow in 2D to optimize solve times. I am running into two specific hurdles: Cooling Channel Definition: When…
My student edition license has expired, and I cannot figure out how to renew it. The Student Edition Bundle does not appear on my Altair Marketplace. Can my account be verified so that I may renew my student edition license?
What is the formula used to generate B-H loops for the Saturable Core inductor and the B-H loop calculator? I have B-H loop data saved in MATLAB and would like to update my scripts to generate K1, Kexp1, K2, and Kexp2 coefficients for use in PSIM. The documentation provides a good way to come up with coefficients from a…

Hello, I am reaching out to clear a few doubts on the way topology optimization is implemented in Flux v2024. When using the SIMP method, what is the penalization applied to? Relative permeability, reluctivity or something else? If possible, I would also like to know the interpolation scheme used for the parameters(s). In…
Hello community, today i tried to follow some tutorials for SimLab with Flux for Magnetic AC Simulations. Therefore it is needed to use the Circuit Designer to setup the Current Source. Unfortunately it is not possible to move, edit by double click, delete, wire or move the Circuit Components. I also tried SimLab v2024.1 -…
