[edit] Types of analysis
The ACELAN have a possibility to solve problems in the following performances:
- plane strain;
- plain intense state;
- axial-symmetric problems.
Existing types of finite element analysis:
- statical problems;
- problems of eigenvalues.
[edit] Materials anisotropy
Some of bodies of general compound construction may have different properties:
- elastic isotropic;
- elastic anisotropic body with any arbitrary type of anysotrpy;
- piezoelectric body.
[edit] Database of materials
There is special material database of elastic and piezoelectric materials. The database has a developed interactive interface. Moreover you have a possibility to add any material to the database.
[edit] ACELAN preprocessor
A geometrical preprocessor of two-dimensional regions provides comfortable tools for geometrical models building (points, lines, regions). The down-to-up technology is used. Moreover you can use a collection of geometrical primitives such as rectangles, circles and so on.
You can use following types of external loadings:
- mechanical point load;
- spased linear loading;
- displacement vector;
- strain vector;
- electroded and non-electroded borders;
- active and passive electrodes;
- any combinations of above.
The two-dimensional triangle 6-nodal finite elements with the elastic and piezoelectric properties are used under the triangulation. The automatic triangulation Delone are applied for the problems.
[edit] ACELAN solvers
The right method of modified square roots are applied for the statical problems.
The eigenproblems are solved by Arnoldi-Lanczos method.
[edit] ACELAN postprocessor
After solving your problems pictures and listings of deformed state and shape are available. You can also see following results:
- displacement vectors;
- electrical induction;
- electrical field tension;
- electric potential;
- strain tensor;
- stress tensor;
- energy properties;
- electric and mechanic coupled factor;
[edit] ACELAN future developments
- oscillation problems;
- problems with acoustic mediums;
- general cylindrical three-dimensional problems;
- new piezoelectric finite elements.
