Society of scientific calculation specialized in Civil Engineering
In order to carry out complex numerical simulations for post-processing of results or for automatic meshing creation, we have built up several programs, sometimes under the guise of a Numerical Tool.
Numerical Applications & Tools
TCP
TCP is the relationship between the Finite Element Program Code_Aster, the meshing builder Gmsh, and a friendly new brand interfase, based on graphics windows and drop-down menus. The modular concept adopted since its creation guarantees a great robustness and a broad range upgrading capabilities (3D geometry, steam transfer, mechanical & acoustical behavior, fire resistance, etc.). For example, in the case of modeling a 2D wall ("mur_2D") using a 1D thermal analysis ("thermique_1D"), TCP v1.0 allows performing :
Analyses :
- construction of a complete mesh of bricks, based on a reduced number of parameters
- taking account of orthotropic behavior of terra-cotta
- heat transfer analysis in stationary or transient state
- post-processing and synthesis of results, clearly and concisely written in a single report
- automatic machines for each computation

3D post-processing at the Points of Gauss
PASTEK
PASTEK (Post-Treatment Aster with Pov-Ray) allows visualization of analysis results, obtained in calculations program (as Code_Aster, for example). The main advantages of this tool are :
- realistic images created by using the "ray tracing" method
- capacity to modify element surface opacity, which allows checking analysis results inside of the structural model
- display of analysis results on the point of integration (points of Gauss), or even in meshing nodes, without applying any interpolation or any other treatment
- creation of snapshots and/or animated images (fixed model or traveling camera)

Follow up and control of Code_Aster® Studies
POSTASTER
This tool is able to follow up internal calculations in the case of a nonlinear analysis. By tracing the number of iterations in each calculation step, or evaluating each iteration's residual, it is possible to determine if nonlinearity conditions are producing important problems for convergence. Based on this additional point of view, user will be able to decide stopping analysis or letting calculations to be continued.

Distant work
MEG2
This one is in reality an adaptation of MEG program, which was developed by EDF R&D. This tool is designed for managing different studies or projects (a complete list of files needed in a Finite Element simulation), as well as executing them in the calculation program Code_Aster. NECS has provided a modification which makes possible to execute calculations from distant servers. MEG2 encapsulates all of the required files and transfer them in a secure package to/from the distant server.
