*DOT, Vector1, Vector2, Par_Real, Par_ImagĬomputes the dot (or inner) product of two vectors.

Performs the matrix operation M2= v*M1 + w*M2. Similar arguments to *DMAT.ĭeletes a matrix or a solver object and frees its memory allocation. *VEC, Vector, Type, Method, Val1, Val2, Val3, Val4Ĭreates a vector. *SMAT, Matrix, Type, Method, Val1, Val2, Val3Ĭreates a sparse matrix.

You can also import from a file or an APDL variable. You can allocate it, resize an existing matrix, copy a matrix, or link to a portion of a matrix. *DMAT, Matrix, Type, Method, Val1, Val2, Val3, Val4, Val5Ĭreates a dense matrix that is complex, double or integer. Commands to create and delete matrices and vectors then you have commands to do basic matrix/vector math like multiply, find dot products, and do Fast Fourier Transformations. Note that you have a set of commands to create the matrix/vector you want, which includes reading from a file or importing an APDL array. Just like parameters and arrays in APDL, the matrices and vectors in APDL Math use names to identify them. As usual, you really need to read the manual entries to get the full functionality explained. The Commandsīelow is a list of the APDL math commands. The entire tool is documented in the Mechanical APDL section of the help under // ANSYS Parametric Design Language Guide // 4. The other is working with sub-structure matrices. The most common uses we have seen is the exporting of a matrix from ANSYS for use in some other program, usually Matlab. All of the commands start with a * character and look and act like standard APDL commands.ĪPDL Math is a tool for users to do two things: 1) get access to view, export or modify matrices and vectors created by the solver, and 2) to control import or modify matrices and vectors then solve them. It consists, at R14, of 18 commands that can be executed at the /SOLU level at any time. Although it runs in a different workspace (chunk of memory in the ANSYS database) it talks to standard APDL by importing and exporting APLD arrays (vectors or matrices). It is an extension to the APDL command language that drives MAPDL. This posting is just going to cover the basics so that you know what the tool can be used for in case you need it in the future, and hopefully motivate some of you to take a long look at the help. There is a lot of capability in this tool. Now it gives you access that you needed custom FORTRAN code to get to in the past… or NASTRAN DMAP, which is really something none of us ever want to do. It kind of snuck in over time, with the developers adding more and more capability each release. And most users don’t even know it is there. It is one of the most powerful, uber-user, deep down under the hood, wrapping your hands around the neck of what FEA is, capabilities in the ANSYS Mechanical APDL (MAPDL) solver.
