It's about cooling during thermal simulation Answered

Hi.

Now I'm doing kind of thermal simulation, HIFU.

But the problem is cooling.

Temperature at skin is going higher and higher. (Over 100 C!! )

Simulation structure is

Transducer

-----------------------

water

----------------------

skin

---------------------

tissue

I think if I can put cooling effect at water, my simulation result could be different (skin is not going to burn anymore...)

How can I put cooling component?

Please help me.

Thanks.

And one more question...

I want to use wsiz in grph function

But when I use this function, I can't save movie at all!

Play time goes 0 sec.

Here is my code.

grph
set imag avi /* Movie generation
end

proc plot save

exec $nexec_loop

grph
wsiz 640 480
colr tabl data 6 /* Set color table for data
plot tmpr rang 37. 90.
imag /* Save frame of movie - creates AVI in folder when model executes fully
end

end$ proc

proc plot $nloops

What is problem?

Please help me...

Hi Hyunjae,

So one thing you could try is setting the boundaries like so:

boun
side xmin tmpr func $baseline

where $baseline would be set to the temperature of skin (37C). This will provide cooling.

The code above for plotting should work fine. Could you send your files to us and I could investigate why this isn't working for you

Best regards,

Oliver
