"The Analysis has stopped because the Solver has stopped unexpectedly" error

[cdelavega]

I am currently getting this error today. I've been following the same recipe and had no problems. There seems to be no problem with the mesh. I ran it yesterday with no problems with a similar application.

Can you attach the support file? This will help to determine the underlying cause of the problem.

[cdelavega]

Will this work?

[srhusain]

No. what you need is the <designstudyname>_support.cfz file. This should be located in the folder up one level from the file you just posted.

[cdelavega]

I tried but it says "the contents of the attachment doesn't match its file type".

[srhusain]

rename the file extension from"cfz" to "zip" and see if that works

[cdelavega]

The zip file is apparently too big to upload in the message forum. Can I upload this in Autodesk 360?

[srhusain]

Please upload to A360 and post the link. Thanks

Hopefull this works http://a360.co/1l5yBcJ

There are at least two issues with the setup:

1) (See attachment)- it appears that your volumetric flow conditions are inconsistent

2) There are only 12 solid elements in your model- you should suppress the related parts to eliminate all solid elements if that is you intent, otherwise the parallel code will not be able to partition the solid elements across an 8-core machine

I ran a similar simulation yesterday as attached with the same approach http://a360.co/1pOb9jP. My intent is to simulate a pressure differential for a mixing device that is submerged in a tank. Because of pressure differential in the tank, there are two different flows. An initial flow rate enters through the device, thus entraining the surrounding liquid and pushing the initial and entrained liquid out. I assigned the boundary conditions and set the mesh and it worked fine.

[srhusain]

Ok, granted that your boundary conditions are not the root cause of the present problem, I cannot guess why your model ran before, but it is possible that the mesh partitioner is having issues with the few solid elements- if you are not running thermal, what is your need to keep these solid parts active?

[cdelavega]

The solid "discs" act like pump of the device. I was told by someone at Imaginit to do it this way.

[srhusain]

You do not have to mesh the solid discs in order to achieve what you are trying because an unmeshed part will act like an obstruction. If all else fails, you might want to start a support case with the the Subscription Center.

I was able to get the analysis to run when i suppressed the stell disc with ID 69

Thank you so much for your help! It's running smoothly now.
