I am new to Modelica and OpenModelica, but I am interested on those simulations.

Recently, I am doing some simulation on engines.

Since I also have some personal usage on modelica, I only need Mechanics module of  Modelica to show in OMEdit.

Is there a way to do so？(The way to only show Mechanics from start ,not to delete other modules after start OMEdit)

I think do some changes on  package.mo and package.order maybe is a way to do so?But I have no idea about how to change it to make it correct for OMEdit after some changes.

I would appreciate if anyone can offer some help on this!
