Timestep size & Max Stagger Iterations
Hello everyone, 1. For vortex shedding simulation (transient), how should I know if my max stagger iterations value is 'enough' or not? what is the good starting value of max stagger iterations. 2. For example: my timestep size is 0.002 + max stagger iterations = 10, if i want to decrease my timestep size to 0.001, should…

Why does the holding plate move unexpectedly in CNTNLSUB, even with SPCs applied?
I have a transient nonlinear analysis in OptiStruct with two subcases to analyze (subcase 2 is a CNTNLSUB relative to subcase 1). In the first subcase, a holding plate engages with the rubber teeth to geometrically position them in their final location, having in consideration their final stress state (which is important…

How to get nodes assigned to a material without any changes in display?
In hypermesh, I would like to get the nodes associated to each material. 1. Currently I isolate each material and get the displayed nodes. 2. I also tried using *createmark elems 1 "by material id" 1 then use findmark to get the nodes Both these above functions displays the elems and nodes associated to the material Is…

Scattering in RL-GO
As I was using the RL-GO solver in a radar application, I noticed that it casts rays from the source that do not end at the "receiver" (the near field sampler). Instead, the end of a ray is denoted with an "S," which the documentation describes as an "observation point." Here is a picture of one ray: My source is the…

Recreating far field pattern from datasheets
Hello everyone, I was wondering if it is somehow possible to recreate the far field of a specific patch Antenna using its technical datasheet. I managed to recreate the 3D radiation pattern using AMAN by recreating the 2D horizontal and vertical radiation patterns from the datasheet and then converting both to a 3D…

Auto - SPC d.o.f.s reason.
Dear OptiStruct Users, I have a question concerning DOF 1, 2, and 3 in the picture next to grid number 78029001. What could be the reason for their presence? I understand DOF 4, 5, and 6 can be between rigid and solid connections, because a solid has only three DOFs and eliminates 4, 5, and 6 from RB2 and RB3 if it is…

Radioss Time History Output Error
I have a model outputting both a T01 file and an H3d file. I would like to have nodal forces/moments for a particular node (TH/NODE output) and forces/moments for a particular RBODY (TH/RBODY) output. I am able to get the outputs in the H3d file if I load that into hypergraph, but if I try to load the time file I am not…
