Hi Mr. Nelson, I was wondering if you answering my question. Tintegral calculates time integral of a variable. My program calculates the variable for entire geometry. If I want to use Tintegral of a variable (scalar) in a specific point in my geometry, how can I use time integral? When we use tintegral on our geometry, which point of tintegral will Fpde give us as an output? Sincerely, Mehdi |

TINTEGRAL is a scalar operator. It requires a scalar argument. If you want to pick a point out of your domain at which to compute the integral, use TINTEGRAL(VAL(<expression>,<x>,<y>)) If you give TINTEGRAL an argument that requires a position, such as TINTEGRAL(VAR1), you will get the value at the last location that was specified in the cascade of evaluations - in other words, a random position. If you want to integrate an entire field, declare a new variable and give it the equation DT(newvar)=<expression>
