Problems simulating COILS [closed]

Hello!

Im trying to simulate the examples from Buildings.Fluid.HeatExchangers. I have problems with the examples that have a coil on it (like Buildings.Fluid.HeatExchangers.DryCoilCounterFlowMassLow). I always get the same error, I don't want a fast solution, I really want to understand what this problem is about. I searched it on internet but I didn't find a hint about it.

I experienced the problem just checking or simulating the examples from the folder I wrote before. The problem is always the same.

[Buildings.Fluid.HeatExchangers.DryCoilCounterFlow: 109:5-109:77]: Component hex.ele[4].initialize_p1 of variability CONST has binding false of higher variability PARAM.

I hope you can explain to me what is going on.

Are you using the latest version of the Buildings library (5.0.1)? And what Modelica simulation tool are you using? There was such an error in previous versions if used with OpenModelica, but this has been corrected, see https://github.com/lbl-srg/modelica-b...

To reproduce, we need to know what versions you are using and what example you are translating.

I'm feeling very ashamed right now. The problem was OpenModelica just decided to load a old version of the library. I reinstalled it again. At the middle of the process, I saw that OpenModelica install old versions of Buildings library. I didn't thought that OMEdit was always uploading a old version with all the issues.

I forced the software to load the current version (5.0.1) and I can simulate models without problems. Thank so much for the fast answer Mr. Wetter.

If I found the way to close this question I'll do.
