Thank you for the report, Kevin. We really appreciate the detail. It
shouldn't be too terribly hard to track down; Rocburn is pretty small.
We'll look into it.
Cheers,
-Mike

We are having a memory issue running Rocstar v1.0. While running the ACM
test case with either Rocflu or Rocflo, Rocstar's memory usage continues to
increase until the memory is filled and the solver crashes. This memory
leak has been verified on two different systems: one, a high end Dell CFD
Workstation running Redhat Enterprise v7.2, and two, a laptop running
Ubuntu 14.04 LTS.The two builds of Rocstar were used to solve the same Rocflu ACM test case
with 4 processors. The used memory for each simulation was charted as a
function of time and the rate of memory increase is identical between the
two systems. See the attached PDF containing the plots.Comparison of Rocstar Runs.pdf
https://github.com/IllinoisRocstar/Rocstar/files/178441/Comparison.of.Rocstar.Runs.pdfIncluded in the plots are information about the Third Party Libraries and
compilers used for preparingThis problem appears to be limited to when the Rocburn module is called -
all of the other test cases, Super Seismic Shock, Elastic Piston, and the
Shock Panel do not exhibit the memory leak. When the same Rocflu ACM test
case was prepared WITHOUT including the '-b' in Rocprep, it also did not
suffer from the memory leak.Please let me know if there is any other information I need to supply in
order to help resolve this issue.Thank you.

Great Mike - thank you! Again, please let me know if there's any other information I can provide.

Hello, I am using Rocstar to simulate the two-phase flow. I have encountered the problem of selecting 0 (ASCII) or 1 (binary) output in the # FORMATS Section in the.inp file, which gives a "ERROR 1005: Window does not exist". Do you have encountered this problem? ?
