COMSOL 6.4 - Global Evaluation and Integration

Global Evaluation and Integration

To get the value of an expression defined with a global scope, use the function mphglobal.

1

Evaluate the total applied voltage, defined with the parameter Vtot:

Vtot = mphglobal(model,'Vtot')

2

To calculate the total heat produced in the busbar, you can integrate the total heat source using the command mphint2. Enter:

Q = mphint2(model,'ec.Qh','volume','selection',1)

The total heat is:

3

Evaluate the total current passing through boundary 43 and retrieve the unit of the integral:

[I,unit] = mphint2(model,'ec.normJ','surface','selection',43)

4

Evaluate the maximum of the temperature in domain 1:

maxT = mphmax(model,'T','volume','selection',1)

5

Evaluate the maximum of the temperature on boundary 43:

maxT = mphmax(model,'T','surface','selection',43)
