偏微分方程与微分代数方程的一致求解方法
Consistent Solving Method of PDE and DAE
摘要
Abstract
compModelica is a multi-domain unified modeling language for modeling and simulation of large andof PDlex physical systems.However,it dealt only with DAE but not with PDE.A consistent solving methodE and DAE was proposed.The PDE was transferred into a series of DAEs with the meshless method of dradial basis function collocation,and was solved by the mature DAE solver in MWorks platform based on Mo-delica.Results show that this consistent solving method realizes the consistent solution of PDE and DAE un-ber the premise of not changing Modelica grammar,and has high accuracy and the convenience of dealing witha oundary conditions,which is conducive to solve complex engineering systems with multi-domain couplingnd time domain and space domain coupling.关键词
