As an example, if you want to write just the fourth value in array A() you would do:.This will only write out nrow times, skipping based on ninc (defaults to 1) But if you don’t want the whole array written, you can control by placing *VLEN and/or *VMASK in front of the *VWRITE command: If you supply an array parameter, *vwrite loops on the parameter from the given index (1 in this case) to the end of the array. The first thing you will notice is no *do loop. You can do something like (just look at the *VWRITE line, we will talk about the rest further on): This is where the real flexibility comes in. PAR1 through PAR19 can be array, scalar, or character parameters. Parameter Arguments for *VWRITEĪs you can see from the command, you can have up to 19 parameters listed on a *VWRITE command. We will cover the first line first, and the format second.

The first contains *VWRITE and a list of parameters and/or arrays to write and the second contains a format statement. *VWRITE is a unique command because it actually uses two lines. Now you have a place to write to, next you need to use *VWRITE to write. We don’t recommend this because other stuff might get written as well to the file. So if you use /output you can redirect to a file instead of the *.out or screen. This is the preferred method.īy default *VWRITE output to standard output – the jobname.out (batch) file or the command window (interactive). This opens the specified file for writing with *cfwrite and *vwrite commands. A Lot Moreįirst off you need to open up a file to write to. Looks pretty simple right, just *vwrite and list what you want printed. Something that every ANSYS user should have in their back pocket. Originally written to write out data in arrays, it is a very flexible and powerful command that can be used to write pretty much any type of formatted output. The way most people do that is with *VWRITE. Sometimes you are running in MAPDL, sometimes you are using ANSYS Mechanical but you still need to write stuff out using APDL with a code snippet.

A very common need in the world of ANSYS FEA simulation is to write text to a text file from within Mechanical APDL.
