Designating Filling System Issues
Hi there! I am a student using my university's license for Inspire Cast. I have run into the issue when attempting to run casting simulations that my simulation will not progress in the solidification stage. It always completes to ~0.15%, but does not progress beyond that. I have left the program running for over 24 hours…

Error in coupling Flux with Matlab-Simulink
I want to couple a Flux v.2025 project with Matlab/Simulink v.2023b. First, I got a .F2MS file from Flux, then I opened Matlab from the Flux Supervisor, and then I selected Flux Link block in Simulink library. Although the time step is the same in the two the softwares, I face the below errors: Error:An error occurred…

MotionView Solver Can't mesh ParaSolid graphics. What should I do?
Hello, I am currently building a Model in MotionView. When trying to test my progress I get following message in my solver window. WARNING: Can't mesh ParaSolid graphics in Post_Graphic/90017. When I examine the results in Hyperview only one of my parts is missing which I suspect to be the cause of the warning, because…

I am getting an Error 99 when trying to simulate a model with CBUSH-Elements. What did I do wrong?
Hello, I am currently creating a FE-Model that has connected parts via screws and bolts. I am using a workflow that creates a 1D-Beam element for each screw and bolt. This 1D-Elemet gets split and a CBUSH-Element gets added. At this CBUSH-Element a RBE3-Spider connects the CBUSH with the inner surface. Here are my settings…

Auto Component generation with Topology/Rectangles tool
In version 2024, if I created a Rectangle with the Topology/Rectangles tool, that rectangle would be added to the "current" Component collector if one already existed. In version 2025, it now seems that even if I have an existing Component collector set to current, that if I create a rectangle using Topology/Rectangles, a…

Modeling of Hypervelocity Impact in Composite Laminates with Altair Radioss
This post presents an Altair Radioss solution to simulating hypervelocity impacts on composite laminate. It is based on Meso-scale modeling of hypervelocity impact damage in composite laminates from Aleksandr Cherniaev & Igor Telichev, published in Composites Part B: Engineering, volume 74 (June 2015) [1]. Figure 1: Bullet…

Total support reaction moment
I have a simply supported model in SimSolid with four supports. Each reaction support has a reaction in only the Z direction (or essentially zero in the other two axes), and zero moment reported. However, when I select all of them in the dialog box to get a total, the resultant moment is quite large in the X & Y direction,…

FlightStream - CCS Wing Meshing Growth Controls Being Ignored
Hi, I have been using the CCS wing meshing tool in FlightStream to create the wings and horizontal/vertical stabiliser for a light aircraft. The mesher works fine without control surfaces, but the moment I specify a control surface it seems to ignore any growth scheme settings. For example, this wing has 160 chordwise…

Is it possible to incorporate the impact of endwinding in 2D Flux thermal study?
I am performing a 2D radial-plane thermal simulation of an electric machine. Normally, the effect of the end-windings is neglected in this study, as it is not modeled. Is there any way to include or approximate the impact of the end-windings in such a model? Is there any way to add a thermal circuit to model it? For…

JKR v1 model and JKR v2 model
I ran two particle mixing cases in EDEM 2025 with GPU CUDA. One case used the JKR V1 model and the other used the JKR V2 model. The surface energy in V2 was set to twice that of V1 (as shown in the figure). No contact radius was specified in either case, and all other conditions were exactly the same. I expected the…
