Cooperation and product development support
We are constantly seeking new opportunities to collaborate in promoting the development of new products. Based on our long experience we possess know-how in the field of numerical (CFD, FEM) simulations, engineering measuring and other CAE activities such as preparation of models and meshing. We are also able to process search studies in the areas of new technologies and elaborate a risk analysis for research and development work. As part of our cooperation, we offer an active form of outsourcing of development activities with the support of numerical simulations, when our employees responsible for the project management take over the task definition during the consultation on customer's premises and thereafter solve the project in daily contact with the customer. If required, we can allocate our employees directly as contractors on customer's premises.
Numerical model preparation
CAD data at the construction output include many, for the CFD and FEM analysis often unnecessary, respectively unimportant details. For preparation of meshes it is therefore appropriate to separate only data important for the analysis and prepare simplified geometry of the computational model.
Separation of the necessary data and model preparation is done in software ANSA (BETA CAE Systems S.A.). The input data for models preparation are required in data format, which represents output of most modelers :
- iges, igs
- step, stp
- vda, vdafs
- ansa
Numerical model preparation for CFD / FEM
Since good results of CFD / FEM analysis strongly depend on the quality of meshes, it is necessary to create correct mesh on the pre-geometry model.
With regard to the computation type we create CFD / FEM meshes of specific size, structure and elements quality. Our capacity allows us to create meshes up to the size of 80 million volume cells. We can create meshes for both stationary calculations, as well as for non-stationary calculations and moving meshes.
As a traditional tool for creating structured, unstructured hybrid surface, volume and moving meshes we use ANSA, TGrid and GAMBIT software, in which we are ready to prepare meshes for your numerical simulations.
Personnel contracting
We offer personnel support directly on the customer's premises to carry out project activities in the fields of CFD and FEM simulations, development of computational models and other activities during product development. Based on contractor agreements, we are ready to provide required number of appropriately trained experts for both short-term and long-term stay at the customer. Typical customer requirements for contractors are: CFD analyst, FEM analyst, mesher (CFD / FEM), an analyst for thermodynamic calculations, an analyst for the thermo-mechanical calculations and so on.
Risk analysis
Integral part of our activities is the development of risk analysis and FMEA documents as required.
Risk analysis - the risk usually doesn't exists in isolation, but it is a combination of risks that may eventually present a threat to the subject. It is necessary to evaluate risks in terms of their possible impact and likelihood of occurrence (including combinations thereof) and focus on key risk areas and suggest countermeasures.
FMEA - The focus of this method lays already in the process of developing a new product, when we define all possible defects (including the manufacturing process), these defects will be assessed in terms of possible impact and likelihood of occurrence and according to the Pareto principle we focus on the most significant ones and in advance propose countermeasures.
