Hello

I want to increase the temperature of a specific part in my geometry so for that I am using 2 things
1. I am creating 2 zones.(flow zone and source zone (Random names are given))
2. Using udf (for source term) and hook it to source zone.

from this, I am achieving my goal.

this is working properly as I want to increase my temperature from 300 to 2500 in few time steps (it will be like a spark)

Now the problem is as my temperature is increasing and I kept density to be constant....my pressure is not changing (1 atm).

My system is closed vessel.

Temperature increase and density are constant ---> then pressure should increase in a specific part.

SO can you please explain why it is happing.

Or any other way is there to increase a temperature od certain region for certain time.


I hope you understand

Thank you
