Also, the solver progress bar doesn't display properly, and solution info folder is always marked as unsolved (both, I guess, b/c solver is tracking progress against a dummy end time: 1000 s). However I'm inherently skeptical of this, as the dummy time value persists for a short time in each loadstep, before the snippet is executed, and I can't be sure it's not affecting anything. Clicking on Display Command Line in the Mechanical APDL Product Launcher gives me this line:nC:MAPDL.

that can be parameterised with snippet arguments (dt = ARG1). Hello,ni want to launch MAPDL from the command line. This overwrites the dummy time value with a new value, based on a timestep, etc. Settime = dt*(nloadstep+1) ! (+1 is needed)Įxecuted at all load steps. Here is the commands that can be used in applying acceleration to the body. at 11:57 am jpasquerell Ansys Employee Why do you not want to use the Analysis Settings option in workbench If you do not want auto time stepping then turn it off for all steps. This is a pain, and I cannot parameterize any these variables (timestep, etc).Ī clunky workaround I have is to leave an dummy loadstep time vector in analysis settings, e.g. Answer: You can use the command snippet to apply linear acceleration to the assemblies. I have to re-edit this, and the substepping options, whenever the timestep, etc. , and insert that into the step control tabular data (Analysis Settings). The is problem is, to define the load step time data, I have to externally create a vector, e.g. (I'm not using USRCAL as I don't know how). HinnThe D command is used for that (see help manual for more info).nnE.g., D,ALL,UY,0.01 applies a Y-displacement of 0.01 to all selected nodes.nnAll the bestnnErikn. The use of load steps over substeps is so an APDL command snippet can be exectued at each load step to apply the feedback load. The TREAD command places data in a Table Array. The TREAD command is more versatile, reading data from a Comma Separated Values (CSV) data file. Background: So I have a transient structural analysis that uses a large number of load steps (>1000) to simulate a system with load feedback (an aerodynamic model which takes velocities, angles, etc. Ansys Mechanical APDL can use the VREAD or the TREAD command to bring numerical data into Ansys.
