Hello~

My name is Dongsig, Shin, and I am an laser micromachining engineer
in Korea Institute of Machinery and Materials (KIMM).

Now a days, I am wondering to solve PDE problem as followed TTM model.

In this process, I can see your website and FlexPDE proglam.
Therefore, I don¡¯t know how to control your software.
Prior to do this, I want to check possibility of FlexPDE in laser application.

Is it possible to solve followed TTM model in ultrashort laser machining using FLEXPDE.
Could you show some script if you have similar sample script with TTM.


Sincerely yours
Dongsig Shin

I composed TTM code using prior sample script in this web site.

But It always happen error message in boundaries as followed.
*FlexPDE gramaar does not allow 'Boundaries' in this location...

Could you find some mistake in my script?

Sincerely yours

1.
Your TL equation is given as
TL: Cl*dt(TL)=G(Temp-TL)
The right hand side looks like a function call, but G is a number. I assume you wanted a multiply sign? "Boundaries" is the next thing in the text, and the parser could not figure out what to do with it after an illegal equation term, so that's where the diagnostic was issued.

2.
You have applied a value boundary condition to Source. Source is not a variable, it is a definition. You can apply boundary condtions only to variable, as they are attached to Equations.
