The definition of the mesh deformation methods is done by creating sub-tasks of type Preprocessor in the task menu. Each preprocessor sub-task is defined on a specific domain, and their domains must not overlap. After your mesh deformation sub-tasks are defined, you can define the setup of the flow problem as usual. As indicated in the name, the preprocessor sub-tasks will all be solved in Ansys Polyflow in specific solvers prior to the evaluation of the main flow problem.
To begin defining the mesh deformation for a preprocessor sub-task, read a mesh and create a task. Then perform the following steps for each domain:
Create a new sub-task.
Create a sub-task
Click Preprocessor for the sub-task type.
Preprocessor
When prompted, enter a name for the sub-task and click .
Define the appropriate domain transformation method, based on the manner in which you want the mesh to deform.
Elastic remeshing
Fixed domain
Rigid translation
The steps for using each of these transformation methods are described in detail in the sections that follow, starting with the fixed domain method.
