Hi @felix_fedi, @marianadu makes a good point to just check with a dyna examples model. You can also just try removing all *Control cards and th...
@ezekiell I think this site will be extremely useful to you in wrapping your mind around the format and what does what. LS-Dyna uses are "card" ...
@rybask1 I mean when you initialize your simulation, what are you putting for memory shown below. I understand that Ansys has recently changed up some...
Hi @nikhillonkar92, I believe that you will need to define an orientation node as N3. *ELEMENT_BEAM N1 - Nodal point (end) 1. N2 - Nodal poi...
Hi @ezekiell, Awesome to hear you are getting into the field! Your first step will be getting the hang of the Prepost UI and the format of the LS-Dy...
Hi @nikhillonkar92, If you're goal is to extract forces between contacts, you should use rcforc (*Database_RCFORC) which will output Resultant Inte...
Hi @kilipeti, I looked at the videos. It was a little difficult to see the point that you want it to rotate around. Could you attach an image that ...
Hi @rybask1, What exactly are you "running"? Just the model by itself? You should at least be able to initialize it by itself so something is going...
@mass Yeah that's really it. I didn't want to say "they should all point the same" since you have parts intersecting at perpendicular joints. And well...
@mass That all looks right to me! Yeah I believe anytime junctions of 2D shells occur prepost will visualize them like this. Another check you can...
Hi @eugenekalentev, If your added mass is 40 g and your original is 6 g (over 600% added mass) that is your problem. Your mesh is probably too fine...
Hi @gmc23, This can be tricky depending on how the model includes are written. I don't really trust LS-PrePost to save out an entire file with incl...
Hi @hafit38, Try double checking that the SSTYP and MSTYP are set correctly with what your SSID and MSID are. For example, you might think you are ...
Hi @bujji23, You should be able to get forces through either rcforc or rbdout. Here’s an overview of all database outputs:
Hi @jazimsohail, @fatihk is right. You would want to set a death time for the contact with the impactor. Make sure the contact is isolated with only...
