<h2> <a name="1"></a>1. Introduction</h2>
|
||
|
|
All hypotheses and algorithms are available in SMESH module via plugin mechanism.
|
||
|
|
Such approach allows easily to introduce new hypotheses and algorithms types
|
||
|
|
to the application. Also, it makes possible the customization of available
|
||
|
|
hypotheses and algorithms list for different users without recompilation
|
||
|
|
of sources.<br>
|
||
|
|
The goal of this document is to describe the process of creation external
|
||
|
|
mesher plugins.

Create your mesher plugin package which will contain the sources files, e.g.

|
|
MyMesherPlugin.<br>
