IsoSurface: Segmentation Fault

swaraj1112

On creating surface vtk files from binary files (each of 467 MB), ISOSURFACE stops with Segmentation Fault. What can be the reasons for this error. I saw a thread where this question was posted but no one replied a solution.

@Alex Please help me out on this one.

Alex

we need you send more information....

After binary files were created, i tried to generate vtk files by using the command 'IsoSurface_linux64 -onlytype:fluid -saveiso surface', but it ended with 'Segmentation Fault: core dumped'. I am using the official version of executable sent to me via link.

Alex

there is no need to add now "-onlytype:fluid"
are you using the latest version 4.4? do you have the problem with that version?

swaraj1112

Yes having problem with that version.

@Alex, urgently need a solution on this one. Ran this simulation for 14 days and have to study this results,

swaraj1112

No worries, Problem solved. Broken File was the issue

@swaraj1112 can I send you a pm regarding your 14 days of simulation? I am just a bit curious, since I might soon have to look at something at a big scale as well. Is this your simulation with 300 million particles or something like that?

Also happy you resolved your issue.

Kind regards

It was Casting simulation (Liquid Metal Flow to the mould stl).
Fluid Particles:14 mil
Fixed Particles: 1.2 mil
Simulation was done for 6 seconds. At first part generation was fast (in 15 mins) but later each part took 1 hour. Maybe there is auto time-stepping when convergence is not reached.

Correction: Simulation was set for 15 seconds.

Thank you! Kind of incredible what a single GPU can do, I imagine it must be some kind of a Quadro or?

Hoping some day to get multi GPU support, would increase speed so much
