I'm trying to simulate the impact problem of a balling to a base in Explicit Ansys. I add a frictional contact between the ball and the base. But it seem Ansys doesn't recognize the contact and the ball is an obstacle with a base. enter image description here enter image description here I try to change many behavior of contact but it seem useless. Also can anyone help me point to the difference between body interaction and the contact ..read more

I have a mesh with a "tecplot" format but i need to use it in "ansys fluent", I found a github repository called "meshio", but i didn't understand how to use it, or maybe it's does not even work , is there any other solutions!! the "meshio" was difficult to understand ..read more

I am confusing about the difference between Modelica and Scade modeling language. It seems that they are both MBSE(Model Base System Engineering) solutions. What is the difference between them ..read more

Both Simulink and Scade Suite can be used as MBSE solution to develop safety critical software. Which is more widely used? In my knowledge, Scade Suite is used in avionics, nuclear power, railway industry. Simulink is used in automotive industry. But I have no idea on the market share of each solution ..read more

I am trying to run Ansys using powershell. I am completely new in powershell environment. The only help I have got from Ansys website and different online forum is running ansys using the following command line prompt (cmd) %ans_path% -b -np %num_proc% -j %job% -run %run% -i therm.inp -o trun.out where %ans_path% , %num_proc% etc. are variables defined early. Reference: https://deepthoughtdocs.flinders.edu.au/en/latest/software/ansys.html How do I run this same code in Powershell? or Do I have to invoke CMD from powershell to run this code? Would appreciate help any direction ..read more

Why do I get an error when using ANSYS PYMAPDL to extract a stress tensor on a named selection? I did check with print(mapdl.cmlist()) and the concerned node does appear in the list. I was expecting to extract the result at the particular nodal selection. However, i gives an error saying it cannot find it ..read more

currently I use the UDF to calculate the DPM concentration in the domain, I set particles uniformly distributed in the domain and use an air conditioner and an air purifier to dilute the particles in the domain (outlet set as escape condition and wall set as trap condition), in my UDF code it only consider the total particle number to calculate the concentration so the concentration remains the same at each time step, I don't know how to consider the trap and escape particles into the code so that the concentration can decrease as time passed. Can someone give me help? The following code is my ..read more

I want to modify the.dll file which is written in C for Zemax Opticstudio. Please help me with how to do that. Is there any way to understand the code written there and then implement it? Also while I am trying to bring it in VSCode, it is asking for including the path for it. Is there any way to learn this as I am very new to this field ..read more

I am using beam elements to mesh line elements with "pre-meshed" shell areas. Problem is that the line normals are arbitrarily assigned to the lines resulting beam cross sections switched at line junctions. For instance, all lines in X-direction have their respective line normals flipped to arbitrary direction at line junction. I want to assign along X-axis to be aligned all in same direction, say, positive X axis Thanks ..read more
