You have to compile the model you want to use. For instance, if you want to use d2q9_SRT
you use:
make -j 4 d2q9_SRT
The -j 4
option makes the compilation in parallel.
The problem is d2q9_SRT directory is missing in the CLB directly. I didn't find it.

It looks like you tried to compile all models. This will probably fail.
Compile only the needed model with make -j 4 d2q9_SRT
. Then you will end up with the CLB/d2q9_SRT/main
solver.
It works now .thanks. Does TCLB provide restart compatibility or do we have some method to decide the convergence of the computation process.
You can save and load the simulation with the <SaveMemoryDump/>
and <LoadMemoryDump/>
elements.
You can use <Stop/
> element for checking convergence. For example
<Stop FluxChange="1e-5" Times="5" Iterations="100"/>
will check the Flux
global integral every 100
iterations, and if 5
times in a row it will be changing less then 1e-5
, then it will stop the simulation.
The d2q9 karmal example gives many warnings?

hello, I didn't find the d2q9_SRT model in the "CLB"' directory. I want to know which model should I compile to run this example file.
