****simulate

Description

This command marks the beginning of a simulator calculation definition. The Z-set program in simulation mode (-S switch) will search this command and interpret all the sub-commands until the next **** level command is reached. More than one simulation block may be included in the input file, which are accessed using the -N <num> command line option.

Syntax

The simulation accepts the following syntax for the problem definition:

****simulate \(~\,\) ***test test_name \(~\,\) ... \(~\,\) ***model model definition \(~\,\) ***solver solver-type_name \(~\,~\,~\,~\,\) solver options ****return

The definition of a ***test is used to specify particular tests to simulate. The tests will be run through in the order of their appearance, using the default output file prefix of test_name. The test test_name is required.

In each test, different loading conditions, output, models, etc may be defined. See the following pages for these commands and their syntax.

Options ***model and ***solver are available as a means to change the default model definition and the default solver method. It can be a great convenience to define these at the ***-level in simulations where there are many tests of the same material. The command syntax for ***model is the same as in the ***test section (see model and solver). Note that this includes the *-level.

Example

The following is an example of a complete simulation file with a single test definition. See the following pages for descriptions of the individual commands.

****simulate
  ***test funny     % define a test name which defines the default output
   **load           % start the loading section
