I'm facing a problem with modelling diffusion in Dymola.
I want to have two seprate volumes (filled with air), which can be joined and thus exchange heat via diffusion.
My approach was using the Mo...

I need to perform an interpolation of some tabulated data in Dymola Modelica, but I can only find a function that does linear interopolation (Modelica.Math.Vectors.interpolate). I really need some...

I was trying to implement a 1D heat diffusion example from the Peter Fritzon's "Object Oriented Modeling and Simulation with Modelica 3.3" based on the Grid Function Finite Difference Approach to 1...

I am using Dymola in Linux. Recently I find I need to update the Modelica standard library from 3.2 to 3.2.1(Got from github).
Anyone knows what I need to set up such that Dymola starts with Model...

I am integrating a relative small Finite Element (FE) model into Modelica. In doing so, I created a Model (Modelica class) that can read the mass (M) and stiffness (K) matrix in Matlab binary file ...

I am trying to slim down a very complex model to improve performance, and noticed big performance changes when I add or remove variables into the signal bus, especially multibody frames.
I am won...

I would like to know:
the most efficient way to install a library in Dymola, so that it appears in my list of libraries in File > Libraries.
is it possible to have it preloaded in my package b...

I would like to know if there's a limit or a maximum for the dimension of a matrix for each known and possible operation we could use on Dymola(Modelica)?
And if it exist to what extent this limit...

Tuning the PID parameter is crucial in the control system development, here is an example of how to do this for just one PID controller.
