Bound parameter is calculated fine but the value that ends up in the result file is the start value ...

Hi,

Seems there is an issue with propagation of the results
calculated by bound_parameter to the result file.
See an example of the problem here:
​http://www.openmodelica.org/index.php/forum/topic?id=446
I actually edited Test.c and added a printout at the end
of bound_parameters and the parameter mod.result1 is correct.
I also added:

 printf("eq2 - mod.result1: %g global: %g\n", $Pmod$Presult1, globalData->parameters[2]); fflush(NULL);

in eqFunction_2 and both global and local data parameters[2] is 1, but still, in the result file we get 0.
Ok, found the error, but I don't know how to resolve it.
We have in callSolver:

sim_result = new simulation_result_mat(result_file_cstr.c_str(), start, stop);

This will write the parameters, but bound_parameters functions is only called later in solver_main!\\
We need to re-write parameter values after bound_parameters\\
We have this error both in the old (maybe also in the new) simulation runtime.

Cheers,

I added Jens also as he worked on the simulation_result_mat.cpp quite a bit.

Another weird thing in the simulation_result_map.cpp in the constructor is that we have rows and cols but they are never assigned any value and they end up put in the mat header and also
a lot of calculations are done based on them. Am I missing something?

Don't bother to work on this, i'm almost done with a fix for c_runtime.
You can port it later to the new simulation runtime.

I'll set this bug to fixed, but the fix should be ported to the new simulation runtime! See SCM Commits.
