Coppelia crashes when using Vortex

[sumi_boss]

Hello,

I'm running a Coppelia simulation from Matlab Remote API and I selected the Vortex physics engine. However, as soon as the simulation starts the whole CoppeliaSim program crashes. I read on the Dynamics module page that I should register on CM labs for a free license key which I did, but I didn't receive it.
Could you give me an idea as to what to do next and how to activate Vortex in Coppelia?
Thanks in advance!

Hello,

you will have to ask again with CM Lab people for a key. Academic licenses are free. But your scene should still not crash without a license key. What version of CoppeliaSim are you running, and on which platform? Can you share a minimalistic and self-contained scene that illustrates the crash?

Cheers

Hello,

I have a Coppelia Sim Edu v4.1.0 and it's running on 64-bit Windows 7 Professional. I also use the 64-bit Matlab R2019a version to communicate with Coppelia. I am attaching a Dropbox link with the scene that I use, remoteApiTest.ttt. The rest of the files are Matlab and Simulink models and functions. I have the UR5 trajectory planned and an external admittance control loop modeled in Matlab/Simulink and I'm sending joint target positions to Coppelia and trying to obtain current positions and force sensor readings back from Coppelia to Matlab. In Coppelia I have slightly changed the joint callback functions so that I have custom PD control.

this setup is almost impossible for us to inspect, or way too time intensive. Try to have a single scene that illustrates the crash, without external dependencies.

Vortex doesn't work in any case. I ran it without any external dependencies and the same thing happened. After that, I tried running it with the existing UR5 model, with your other existing examples, even in empty scenes and it crashes every time. As soon as I select Vortex and start the simulation the whole program crashes.

Strange. So CoppeliaSim loads normally (including the Vortex plugin), but as soon as you start a simulation using the Vortex plugin, even with an empty scene, it will crash?
Did it already crash before installing the Vortex key?
What is the crash message?

Cheers

Hello,

Yes, Coppelia loads normally and so does the Vortex plugin. I checked the console window and it says plugin ''DynamicsVortex': load succeeded. The program and the simulation work fine until I select the Vortex engine and start the simulation after which Coppelia crashes, even in empty scenes. However, I still did not get the key from CM Labs, but as you said, it should work anyway. I will try getting the key from CM Labs and then see what happens. I don't know what you mean by crash message. When I start Coppelia again after crashing it does show a dialog box that says:

It seems that CoppeliaSim crashed in last session (or you might be running several instances of CoppeliaSim in parallel). Would you like to try to recover auto-saved scenes? (see also CoppeliaSim's installation folder for backuped scenes).

But I don't run several instances of CoppeliaSim in parallel.
I would appreciate any advice as to how to fix the bug with Vortex.

I unfortunately cannot reproduce the crash. Does it also happen on another machine? Maybe the problem is linked to Windows 7?

Cheers

Hi,

Yes, I think that has something to do with it. I will try it on another machine with Windows 10.

Thanks!
