This problem is solved. Thank you.

Sandeep

You don't happen to know how you solved it by chance, I have a similar problem

Getting rather annoying spending time building a model only for it not to be able to be loaded later on.

It has taken a while for me to figure out that. Let me know If I can help you with your problem, unless it is already solved.

Well any help is appreciated,

I have no idea why but simply altering the model and saving it, (sometimes) and then later trying to re upload causes it give the same error and the model is now useless and i have to remake it from scratch or an older file.

Here is part of the error

I got couple of suggestions(by the first idea I got from your explanation). These may be silly and useless, but that particular error you posted went off by doing these things

i.) One weird thing I observed is, When I connect my COMSOL Multiphysics to server and try to upload already created .mphtxt file, I got to make sure the eclipse window is closed completely and not running. In short, Comsol didn't like eclipse window open, when I am attempting a connection with server or importing the file.

ii) Did you try using a different file name ?

Finally, can you elaborate on the situation the error arises, like where you are altering and saving the model(the imported one in comsol or you are altering the java code in eclipse)?

Hi,

I created a geometry in Eclispe(COMSOL API) and saved that in ".mphtxt" format. When I try to import through server it shows the following error:

Dear Sandeep
How can one save .mphtxt or .mphbin file in COMSOL?
I want to save my mesh or geometry in terms of .mphtxt file from comsol.
Thanking you.

Yes, I got it.
Thanking you.

how you will solve it
