The built-in structure group in the software not only enables modification of global parameters (relative position, rotation) or script variables, etc. Add the Layer builder to a Structure group. addgroup : Adds a container group to the simulation environment. Analysis groups are container objects that can contain any simulation object and associated script functions which can be used to customize data analysis. Note that the myscript string uses the escape character \n for new line and \" for double quotes within the string. Oct 27, 2021 · I'm working on scripting a simulation. If a group with name "group_name" already exists, then the objects are added to the existing group. The material is set as an input parameter for the structure code, and the script in the structure group sets all the objects to the desired material. The final result should look like the screenshot here. For overlapping geometries the mesh order is respected, otherwise they are resolved by tree order the same as in standard meshing. Description. Creates a structure array. Rotate the structure group such that the layers now lie in the XZ plane. copy(dx); Same as copy; but with a specified move of dx. Change the name of your structure to 'object'. Script commands that add or modify simulation object use the groupscope property to know where to act within the object tree. Move your structure named 'object' into the array_group. For example, suppose we want to create an array of hemispheres. The name of the structure group includes the original number of layers. nza flt fhtdjp ydhlme mgyfu crsud ywbk tncxn ykdtp wzsj
