heatmap throw an error

[iJokerify]

Hi All,

I have a problem with jpeg output. The output throwing an error during simulation. Log:

[Timer] step=800; percent=10; passedTime=13.022; remTime=117.198; MLUPs=3.61853
[LatticeStatistics] step=800; t=0.2; uMax=0.387785; avEnergy=0.00777169; avRho=1.11122
[setBoundaryValues] step=850; maxVel=0.431187
...
[setBoundaryValues] step=1200; maxVel=0.736322
[Timer] step=1200; percent=15; passedTime=19.333; remTime=109.554; MLUPs=3.40295
[LatticeStatistics] step=1200; t=0.3; uMax=0.73463; avEnergy=nan; avRho=nan
"./tmp/imageData/data/heatMapEuklidNormphysVelocity.p", line 21: warning: matrix contains missing or undefined values
[setBoundaryValues] step=1250; maxVel=0.777759
...

First and second images are looks good, but thrid and all next are broken. Looks like white square, instead of speed field.
Help, please!

Grateful,
Sergey

Dear Sergey,

your simolaton has diverged (avRho=NaN and uMax is quite high). That is the reason for the error. The heatmapWriter seems fine!

Dear Mathias,

yes, i saw it. What could be reason for this?

Grateful,
Sergey

I dont know your set-up, but usually the simulation turns unsrtable if the resolution is not enough to resolve all features or if you set some unphysical initial or boundary conditions. Best Mathias

Dear Mathias,

thanks for your reply! I’ll try to increase resolution and if problem will not solve i’ll write then.

Grateful,
Sergey
