How can I illustrate 3D directivity pattern of a MIMO array
Hello, I want to illustrate 3D directivity pattern of a MIMO array. How can I do this? What I have done till now is that I have defined coordinates of transmitters and receivers in EDITFEKO. But, I do not know how to illustrate 3D directivity pattern of my MIMO array. If it is possible, please provide me with a sample feko…

Changing simulation medium
Hello, can you somehow define simulation material without defining specific 3D model? I wanted to simulate antenna beneath the earth to make a scenario with "infintie" burial dimensions. I kept using sommerfeld integrals from Construct->Structuers->Planes/arrays->Plane/ground. Basically is there anyway to fill "white…

EDEM - Stress relaxation
Hello, I hope this finds you well. I am trying to perform a stress relaxation experiment in which the force increases gradually from 0 to the maximum force of 42 N. After reaching 42N, it is held constant for 50 secs and then decreases gradually. Just to take things bit by bit, I decided to start with the gradual increase…

Altair Flux Frozen Permeability Macro
I have been trying to get the frozen permeability macro to work but I keep getting results that show the permeability not changing with time/with the position of a rotor in a motor simulation. I don't know what is causing these incorrect results but I have tried it one multiple different models and keep getting the same…

automating a .dpwx
I created a dmod file that retrieves data from a PDF file but my client wanted to remove duplicates. So I worked on Data prep studio to remove duplicates and created a dpwx file. These treatments are automated with a .bat on the server and it works very well with the dmod (before creating the .dpwx) but we cannot get the…

Strain rate effect on composite material (/MAT/COMPSH)
Hello everyone, I would like to enrich the material card of a composite material with the effect of strain rate, using the parameter c, but I have the problem that both conditions of low strain rate and high strain rate are affected by this introduction. In particular, the curves of both specimens get higher. In this…

"The problem must not have circuit with MD3TWOM, MD3SCA formulations"
I'm trying to use non-meshed coils and I'm running into this error when I try to solve. Under the electrical tab for the coil editor, I have associated an electrical component from the circuit for both coils. I don't have any coils that don't have an associated electrical component, or any electrical components without an…

save only a part of time integration
I am running motionsolve with a template with 2 or 3 <Simulate> commands. The solver uses sensors to decide when to stop one time-integration. These are dummy time-histo. Only the last time integration is of interest. Is there any way to allow plt and all the output files to chop the time histo and save only the last…

TCL Hypermesh syntax again: loop to store elements
Hello, Here again on my script, thanks to @Michael Herve and @Marc Arnold I go ahead little by little. Now I try to store in a set some elements depending of their coordinates. To simplify here, I have just a row of nodes, 2 rows of elements, and I would like to store elements only if their centerX is bigger than the X of…

PSHELL Formulation for Multiple MIDs
Can you please help me understand how the MID1, MID2, MID3 and MID4 entries on a PSHELL card work together to represent the complete ABD matrix of a laminate? I was reading the documentation, which states that only G13 and G23 are needed for the MID4 entry. If this is the case, how is the extension-bending coupling…
