Problem while iterating on records
Problem while iterating on records
Hello,
I’m having a quite strange behaviour with OpenModelica while iterating on records. At the beginning I thought it was my fault, but I am receiving also bad calculations from models in Modelica.Media. Is it a known bug or is it my fault? I attach a file with one very simple example. Result is correct in Test1, but not in Test2 or Test3. I’m using OpenModelica 1.13.2 64 bits.
Someone one can help?
Thanks
Thank you
Re: Problem while iterating on records
This is a known bug (https://trac.openmodelica.org/OpenModelica/ticket/2858) that was fixed in the new front-end. Please use the latest nightly-build:
https://build.openmodelica.org/omc/buil … ly-builds/
Code:
// t.mos
loadFile("Structure.mo"); getErrorString();
simulate(Structure.Test1); getErrorString();
val(A, 1);
simulate(Structure.Test2); getErrorString();
val(A, 1);
simulate(Structure.Test3); getErrorString();
val(A, 1);
With current front-end:

Re: Problem while iterating on records
Thank you very much. I will try.

Re: Problem while iterating on records
Hi Adrian,
I installed v1.14.0-dev-26644, that solved the iteration over the array of records for the example given, but I am still having problem when the iteration is over an array of records that contains a Real array inside.
I attach the file. Test21 is OK, but not Test22. The new frontend gives the following error:
[1] 00:08:55 Translation Error
[CodegenCFunctions.tpl: 6583:13-6583:13]: Template error: ASUB non-scalar {{5.0, 50.0}, {10.0, 100.0}}[i]. The inner exp has type: Real[2, 2]. After ASUB it is still an array: Real[2].
The old frontend gives no error, but does a bad calculation.
Am I trying to do something forbidden by the Modelica language?
Carlos
Re: Problem while iterating on records
This is most likely a bug. I made a ticket for it and we will fix it: https://trac.openmodelica.org/OpenModelica/ticket/5616
You can fix this by using:
Code:
A:=A+sum(test[i].Tc);
in Test22.

Re: Problem while iterating on records
Thank you again.
In fact there is no problem if you make the iteration manually, by indexing 1,2,...
