An innovative approach for parallel mesh generation has been developed and successfully implemented. The parallelization strategy is based on the domain decomposition. Two levels of domain decomposition have been considered - model level and model entity parametric tree level. The discretization of model entities is based on generalized parametric tree data structure and application of templates. A very favorable ratio between the computing and communication has been achieved and also satisfactory load balancing has been evidenced. A penalty is paid to out weight the overall simplicity of the algorithm. The quality of the final mesh depends not only on the mesh size variation but also on the model parameterization. The restriction on the model topology also results in some reduction of the modeling flexibility.
