Surface variable loading. If Statement

Status: New Idea

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
