Hello.
I am trying to run this example from dynaexamples.com:
https://www.dynaexamples.com/icfd/advanced-examples/windturb
I am using MPP LS-DYNA R12.0.0, Platform MPI.
The specific command that I am using via a Cygwin shell is:
$ time -p "/cygdrive/c/Program Files (x86)/IBM/Platform-MPI/bin/mpirun.exe" -np 8 ls-dyna_mpp_d_R12_0_0_winx64_ifort170_pmpi.exe memory=1000m i=main.k 2>&1 | tee main.txt
So I am already using double precision and it fails when it tries to start the ICFD solver.
Here is the log:
$ time -p "/cygdrive/c/Program Files (x86)/IBM/Platform-MPI/bin/mpirun.exe" -np 8 ls-dyna_mpp_d_R12_0_0_winx64_ifort170_pmpi.exe
i=main.k 2>&1 | tee main.txt
mpirun: Drive is not a network mapped - using local drive.

I don't think that this example should take 1000m words to run, but I tried to set it incredibly high to try to ensure that there aren't problems.
It's running on a HP Z420 workstation, with an 8-core Intel Xeon E5-2690 (v1), with 128 GB of RAM, in Windows 7.
(It has been my experience that almost all of the other examples from dynaexamples.com will run fine, as-is, so I am not really sure why I am having troubles trying to run this example.)
Any ideas or suggestions as to how I can resolve this would be greatly appreciated.
I started having this access violation 157 error a few months ago, never had it before.
I have contacted support from LSTC about this problem a few weeks ago and they told me it was a problem mostly/only happening with SMP on windows platform.
However this error still happens every once in a while even after i switched to MPP. It seems like a lot of forum posts have been coming up in the last weeks about this problem. I am wondering if it could be a problem coming from new versions of LS DYNA solver
Yeah this is mainly an issue with SMP and implicit simulations. The most concrete solution that I found to the issue was to use a version of LS-Dyna with double precision. So in the solver name you want to use the version that has "_d_" not "_s_". Like @davidbenoit, there are several threads on this forum regarding the topic that may have more detail for you.
Yeah, I've read those threads already.
But as is it shown, this is why this is different because a) this is for ICFD, as opposed to an implicit solution and b) as noted, I am already using the double precision, MPP solver, which is recommended for ICFD solutions.
So...beyond that, it would appear that the "usual" tips to address/solve this has already been employed and I am still getting a forrtl (157) error, shown above.
So I didn't know if there was something else that I can try to resolve this issue.
Thanks.
@alpha754293 I see. sorry for the delayed response as I've been away on vacation. Personally, I don't run across this problem often, but from doing some research I found that the above tips were the most common solutions to this issue. Aside from that, have you tried using an older solver? v12.0 is like brand new so there may be issues. Maybe try 10.2 or 11.0?
*Edit: I just saw in the example that it requires v12.0 so my suggestion wouldn't make sense. You can always try to contact LSTC directly about the problem, especially since you are just trying to run one of their example simulations.
Thank you for your help.
I wanted to see how much experience the community may have with LS-DYNA's ICFD solver.
Thanks.
