i just change a name a file and name of block that make my model have a problem in solving

Hi, i'm student and new for this simulink matlab and i try to simulate a Partial-Discharge model

i have one models that is work fine, curve is good, i'm rename a blockname and "save as"file with another name.

then i close all tab and open my another name file it's was the same model from my previous file(this file is run well) and my model work not a same.

(first pic is a model that work fine)

my new model(second pic) is work slow,error etc.

now i'm confuse what happend, i'm just only rename but a model doen't work as a same.

best regard

Hello. The second picture shows that you have unsaved changes. You could try to save your model before running the simulation. Maybe also close other loaded systems if needed, with "bdclose all".
