Description

Technical field [0001] The invention relates to the field of computer-aided engineering, in particular to a multi-physics CAE system based on a cloud computing platform. Background technique [0002] In real engineering, there are many physical fields, such as temperature field, stress field, electric field and magnetic field, etc. All belong to physical field, and many of the problems we have to solve are the superposition of these physical fields, because these physical fields directly influence each other. For example, when steelmaking, the temperature will affect the stress distribution. [0003] The superposition of multiple physical fields is called the multi-field coupling problem, which is also a kind of coupling. [0004] With the rapid development of computer technology, in the engineering field, FEA (Finite Element Analysis) is increasingly used for simulation to solve real engineering problems. Over the years, more and more engineers, applied mathematicians and physicis...
