Issue Solving in Explicit Dynamics, "A General Failure Occured..." 1

[ssanks]

Hey, I'm new here (signed up 5 seconds ago), but I have been having this issue for about a week now.

I'm trying to get ANSYS Explicit Dynamics to solve a model of an oval shaped object hitting a plate at an angle. I have green check marks everywhere (I have defined everything I am supposed to). I'm using an Ogden 2nd Order hyperelastic model for the oval object (supposed to be a simple shoe sole model) and just structural steel for the plate it's hitting. I have defined all of the parameters in the Ogden 2nd order equation. The issue is that when I hit "solve", I get the following readout from the solution status window:

After that, I get "a general error has occured".

I can't find anything on the engineering/physical parameters end that would cause a problem. Everything is well defined and legitimate from an physics/material perspective etc. I've verified my licensing, I've even gone from Windows 8 to Windows 7 to see if that made a difference, and still no luck in getting a solution.

I have no problem solving static structural problems, or transient structural problems, but my computer doesn't want to solve (or ANSYS doesn't) explicit dynamic problems.

Any ideas on what could be causing this behavior?

PS: I have tried other models in the explicit dynamics. Just a ball dropping on a plate, and it still doesn't solve.

Any help is greatly appreciated!!!

For anyone who has experienced what happened to me (above), the answer, at least in my case, was that a firewall was rejecting connections from the RSM, most likely because of a VPN I was using.

If you are using a VPN, first try turning it off (if you can, i.e. don't need it for licensing). If that doesn't work, specifically tell your computer to allow connections on ports 8145 and 9145.

Hi, I am facing the same issue and yes, I am also using the VPN for licensing. Could you give more details on allowing the two ports? Are they TCP or UDP? It is much appreciated if you could share the step by step guide.

Thanks.
