Loops

loop over a block of lines in the input file

Use (nested loops) in the input file.

begin_loop{"LoopVariable_i", iBegin, iStep, iEnd} line that might contain &LoopVariable_i & begin_loop{"LoopVariable_j", jBegin, jStep, jEnd} line that might contain &LoopVariable_i& and &LoopVariable_j & begin_loop{"LoopVariable_k", kBegin, kStep, kEnd} line that might contain &LoopVariable_i& and &LoopVariable_j& and &LoopVariable_k & end_loop end_loop end_loop

The names &LoopVariable_i&, &LoopVariable_j&, and &LoopVariable_k& are free to be chosen by the user. The values iBegin, iStep, iEnd, etc have to be integers. Example: Place a raster of cubes in the geometry.

begin_boundary_elements{} begin_loop{"iLoop",1,1,18} begin_loop{"jLoop",-2,1,2} BND_cube &AliasForTheCubes& -1 -1 -1 1 1 1 rotate{0,0,0,[3*rand(1)],[3*rand(1)],[3*rand(1)]} scale{&H_min&} offset{[&iLoop&*2*&H_min&],[&jLoop&*2*&H_min&],[0.6]} end_loop end_loop end_boundary_elements

The cubes are randomly rotated and given a regular offset.
