Hello, I am currently using the SimLab v2026 Student Edition. I have a question regarding the thermal-fluid analysis of a battery segment using the Solution - Flow tool. (I apologize for any unnatural expressions; I'm relying on a translator for this message.) The model geometry is as follows: The area highlighted in green…
I currently have two parts with an interference fit of 0.55mm. When modeling the actual model, it was through penetration, and the mesh division was also through penetration. I set Clearance=-0.55 in the optistruct contact, but the mesh nodes remained through. Is this correct? Or do we need to manually move the grid nodes…
Hello, I would like to restart my simulation from a previously run state and treat it as a new initial condition. Specifically, I run the simulation for 10 seconds, then I want to take that state and restart the simulation again from 0 seconds, applying different conditions or changes from that point onward. Could you…

Hello, I am currently running a mixer simulation. I am simulating a mixer that blends three different types of particles, and I am wondering how the initial values for the EEPA model should be set. For the particles themselves, I determined the parameters using the angle of repose via the Open Powder Wizard, and I left the…

Hello, Is there documentation for how the spherical mode data is organized in the .sph file? I am looking to import this data into MATLAB or Python, but there is no explanation for which data entries correspond to TE/TM modes, and to which order n,m in the expansion
I am looking to design a metasurface patch antenna on CADFEKO. I am modeling first on a infinite ground plane. The patch antenna is fed with a coplanar waveguide, is it possible to do coplanar waveguide on infinite ground plane? If so, how can I go about doing this? Any other ideas if this is not possible? See files below…
Hello, I have used extensively used both MAGMA and ProCast previously. Assigning temperature-dependent heat-transfer coefficients (HTC) between the mold and the metal was always of utmost important for accurate simulations. When I look in the material file for mold material in Inspire Cast, I see that I can assign a…
I am a BEng (Hons) Civil Engineering student conducting research on the structural robustness of existing buildings through roof-level retrofitting. Using S-FRAME, my work focuses on modelling a roof-level retrofit beam, its anchorage to the 1st and 2nd floors, and the simulation of a ground-floor column removal scenario.…
