To start, we set the loan30000 for the 30,000 car loan and payments equal to 0 since no payments have been made yet. Using a DO UNTIL loop, you can easily calculate the number of payments it would take to payoff a 30,000 car loan. This example only intends to show how the mesh used in this sample problem has been generated. Example 1 Calculate Number of Payments for Car Loan using DO UNTIL. Note that toughio is not required at this preliminary stage of the pre-processing. At bottom left of GMSH’s windows, camera can be reseted using X,Y,Z and 1:1 (scale) buttons. The mesh can also be generated from scratch directly in Gmsh either using its GUI and/or its internal scripting language. The camera can be adjusted using the mouse: rotating ( left click), translating ( right click) or zooming ( wheel). In GMSH, go to files->open ( CTRL+o) and open the file, or type gmsh square.geo in a terminal (warning: this open a new instance of GMSH (which is very light by the way!)).Ī square should have appear in GMSH’s windows. The negative sign flips ordering of the points making up the line thus to be (6,7) becomes (7,6) etc. But this is backward with respect to clockwise orientation. Point(1) = // Setting a label to the Surface For example, Line Loop (1) consists of lines made up of points (6,7) (7,8) (8,9) (9,6). pygmsh combines the power of Gmsh with the versatility of Python. The loop body can contain any valid script command. The body of the loop contains the code that you want to have repeated. square.geo: h = 1 // Characteristic length of a mesh element A finite element mesh of a model is a tessellation of its geometry by simple geometrical elements of various shapes (in Gmsh: lines, triangles, quadrangles, tetrahedra, prisms, hexahedra and pyramids), arranged in such a way that if two of them intersect, they do so along a face, an edge or a node, and never otherwise. The header dictates what the loop is working withnumbers or strings, for exampleand what the end condition is that will stop the looping. Copy/paste the following code in a new file, named e.g.
