I am setting up for a "FREE SIZING" optimization, of a CQUAD4 only structure… yup… Shell Thickness design variable(s) I set up: DRESP1 1 TOT_MASS MASS DRESP1 2 FRSTMODE FREQ 1 DRESP2 3 COMBINED 222 DRESP1 1 2 DEQATN 222 … blah blah blah (this is not where it fails) DESOBJ can occur in ONLY ONE PLACE in the Case Control…
I am trying to install PSIM, but this message error appears when trying to activate my license. I did installed PSIM, but i formatted my notebook, and now i can't install it. I have the same hardware, but i can't deactivate the present license. How can i deactivate?
I am trying to create a contact model for an opening hinge. The purpose is to get force reactions on the fixed constraint (later bolt group) that holds the hinge. The hinge is actuated by a Torsion spring (Spring Mass Damper in MotionView) with preload of 90 deg and KT = 0.05 I have simplified the hinge just to the contact…
Hi -it doesn't appear that Hypergraph can read multiple subcases from a punch (*pch) file at once. The punch file is from an Optistruct run and has frequency response functions (FRF) curve data within…. in my case vibration transfer functions in velocity to/from several locations in a model. Converting the file to a CSV…
Is possible plot strain Z1 or Z2 material orientation ? Does the symbolism z1/z0 or z2/curve mean the same thing?
Hello, I am currently planing a big simulation that needs to be repeated several times with different excitation sources(voltage sources for farfield calculations, mostly). Is there documentation on what setups and settings to use to minimize total simulation time? I assume that if I setup the problem as different…
Hi, I am trying to perform a characteristic mode analysis for this conformal antenna, but every time I finish the simulation in postfeko, I see a warning that "This mode was not calculated over the entire range, more modes should be requested." This issue occurs every time I request more modes. How can I get the result…
RE: [EXTERNAL] FW: 070225 Download of my AI Studio for students HI Antonio, You need to perhaps reinstall the software, it is essential that the selection in preferred license is set to Altair Units and you click OK, you will then be asked to restart the application (not the computer). Please try deleting the temporary…
Hello everyone, I am currently trying to simulate an ADS-B transmitter antenna in FEKO. The antenna design is done, and I want to change the source voltage to a desired signal (PPM signal), which has been logged in a CSV file. Is there a way to import the CSV file into FEKO and generate the signal? Thanks for the help.…
Hello everyone, I would like to get help with the representation of the tangential forces in hyperview with a different coordinate system than the existing one. I have a model that is not oriented to the coordinate axes so I have to place a secondary coordinate system. How could I place such a coordinate system? What would…
