OpenModelica: Errors about missing 'each' statements

Created by: jnettels

Describe the bug

When using certain components with OpenModelica, errors like this are shown (while Dymola is not complaining): [AixLib.FastHVAC.Components.Storage.HeatStorageVariablePorts: 164:3-171:26]: Non-array modification ‘"K"‘ for array component ‘unit‘, possibly due to missing ‘each‘.

I found them in:

• AixLib/FastHVAC/Components/Storage/HeatStorageVariablePorts.mo
• AixLib/FastHVAC/Components/HeatGenerators/CHP/CHP_PT1.mo

To Reproduce

Use these components in an OpenModelica simulation.

Expected behavior

Simulation should run instead of throwing an error.

System and software specifications

• AixLib 0.9.1
• OpenModelica v1.14.1 (64-bit)

Approach to solve issue

Inserting the 'each' statement solves the issue easily. I am linking a pull request.
