报告摘要:
Advanced problems in Mechanical Engineering and Physics require numerical solutions, as analytical solutions can no longer be found.
With these problems becoming more and more complex, the number of unknowns or the number of degrees of freedom is quickly
approaching 10^9 to 10^10.
The current talk will describe two ways of limiting the computing time for these large problems on medium cost computers
(say 10 k$).
The first way deals with Advance Numerical Methods, in this case MultiGrid. MultiGrid allows the user to solve large and complex problems very rapidly and efficiently.
The second way deals with dedicated hardware, since two decades Graphical Processing Units (GPU) have shown amazing
price/performance characteristics. Engineers can to use the GPU power to solve huge problems in three different ways:
- Libraries exploiting GPU exist for many codes (ABAQUS, ANSYS, AUTOCAD, CATIA, FLUENT, MATLAB, .....)
- Open Acces Code
- Programming Languages (CUDA)
With the rise of Artificial Intelligence (AI), running on (NVIDIA) GPU's the development of new and more powerfull GPU's
has seen an acceleration, the spread of AI provides a big market for these GPU's, keeping prices down.
Engineers can benefit from these development to solve very large problems, by using one or BOTH tools (software & hardware).
