Surface variable loading. If Statement

Surface variable loading. If Statement

Currently all functions used in surface variable loading are continuous.

Multiple or discontinous functions can be applied by splitting the surface.   For example, applying wind pressure to a cylindrical object like a tank requires two functions to apply pressure around the full circumference.  A simpler and more flexible option would be to include an IF statement in the available surface variable functions.  Even better would be a multi-line description (or 3 way IF) of a surface variable load to apply patch loads or functions that can be turned on and off.

e.g. A patch load or temperature could be applied by say.

x < x1 then zero

x1<x<X2 the some value or function

x>x2 then zero or some other function

Simplest way to solve this problem is to split target surface to 2 or mor, and than apply pressure for those surface that you need.

 

But you are right that different functions, if statement can be usefull for solving simulation problems
