Adaptive Multi-Grid Methods for Parallel CFD Applications [PDF]

, 2014
Computational fluid dynamic (CFD) computations are memory and time intensive and need to be executed in parallel for larger computational domains. In order to produce physical accurate solutions, adaptive grid setups have to be chosen as the memory and ...

Forward kinematics for 6-UPS parallel robot using extra displacement sensor

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
Many assembly modes exist due to multi-solutions for forward kinematics of 6-UPS parallel robot. However, the existing theoretical research results have not been well applied to the real-time control, because of the complexity of the forward kinematics ...
