Restart (continue) calculation?

Sergey

First of all, thank you very much for your development work and making the DualSPHysics package so readily available.

How I can restart (continue) calculation?
For example I run CaseDambreak_win32_CPU.bat
Obtain in out directory files: CaseDambreak.bi2, Part0000.bi2, PartOut.bi2 and so on.
How I must modify bat file for calculation from Part000N.bi2?

Any help is appreciated. Thanks

Alex

you can restart a simulation using the command line
please check the help of the code typping DualSPHysics.exe -h

and you will discover the option: -partbegin: begin [:first] dir

That doesn't really help. All that option "-partbegin:" does is to rename the staring Part number. The solution still resets to the beginning. It never picks up at the latest Part.

You need to make sure that, in the batch file, the script section which creates the directory_out (and deletes your old one in this case) is removed or commented at least. You need the Part files contained in that directory in order to resume your previous simulation. I've tried this, it works.

module load cuda/4.0
echo $LD_LIBRARY_PATH

cd $PBS_O_WORKDIR

name=Periodic_3k
dirout=${name}_out

GpuSphProcessor="../../EXECS1/sphgpu"

# CODES are executed according the selected parameters of execution
errcode=0
hostname

if [ $errcode -eq 0 ]; then
export OMP_NUM_THREADS=4
$GpuSphProcessor $dirout/$name $dirout -svres -gpu > /dev/null
errcode=$?
fi

if [ $errcode -eq 0 ]; then
echo All done
else
echo Execution aborted
fi

This string:
GpuSphProcessor $dirout/$name $dirout -svres -gpu > /dev/null
how must be?

Sergey

continue isosurface:
$isosurface -dirin $dirout -first:106 -last:200 -saveiso $dirout/Velocity -onlytype:-all,+fluid -vars:-all,+vel,-rhop,-mass,-id
I've tried this, it works

Alex

We try to test and release stuff we are sure that works!!!

For example:
%dualsphysics% %dirout%/%name% %dirout% -svres -cpu -partbegin:begin[:0]
Result:
*** Exception (JCfgRun::ErrorParm)
Text: Parameter "-partbegin:begin[:0]" unrecognised or invalid. (Level cfg:0, Pa
rameter:4)

Execution aborted.
Press any key to continue . . .

What is wrong?

Sergey

Correct string is:
%dualsphysics% %dirout%/%name% %dirout% -svres -cpu -partbegin:PART[:1] MyTest2D_out

Hello,

For example, if you want to restart your simulation from the file "Part0136.bi2" located in the folder "mycalcul_out", just modify your GPU.bat like this:

%dualsphysics% %dirout%/%name% %dirout% -svres -gpu:0 -sv:vtk,binx -partbegin:136[:137] mycalcul_out
if not "%ERRORLEVEL%" == "0" goto fail
