I hereby describe an issue I’m confronting when dealing with arrays in my models.
I kindly ask for your help to understand how the issue could be overcome.

**Expected/Desired Behaviour:
**I want to export an FMU with array dimensions as fixed parameters which I could modify before initializing the simulation.

**Observed Behaviour:
**When I export the model the array dimension has causality = local, variability=constant and is thus not modifiable.

Test code:

`model ArrayDimExample

parameter Integer N = 5 “array dimension”;
Real A[N] “my array”;

equation

for i in 1:N loop
A[i] = i;
end for;

end ArrayDimExample;`

Software Version:
Dymola 2024x Refresh 1, 2024-04-12
FMU export settings:
Type: Model Exchange + Co-Simulation
Version: 3.0 (I also tried 2.0 with same results)
Active flags:
`

• Include source Code
• Export with string parameters
• Copy resources to FMU
• Show dialog when exporting
• Evaluate False on Export Parameter (I also tried with this flag off, same results)`
  Thank You in advance for your kind support.

Kind regards,
RF
