WARNING: SOLVER PROBLEM. NUMERICAL SINGULARITY WHEN PROCESSING NODE 2654 D.O.F. 3 RATIO = 1.05990E+11 I refined the contact pair (TIED,ADJUST= YES) to ensure that the slave nodes are tied to master. could you please help me? best regards. ...
The main challenge for the researchers is to develop increasingly sophisticated and efficient numerical methods that allow obtaining increasingly accurate solutions maintaining low the computational effort. Due to the non-local character and to the weak singularity of the fractional operators, a considerable...

Numerical singularity when processing node PART-19-1.1 D.O.F. 3 ratio = 108.494E+09 查百度后是出现刚体位移,但是我在初始部把所有部件全都完全固定还是出现这种警告,一直不收敛,请求帮助 分享11 mathematica吧 海天热血 NDSolve中使用了一个只能接收常数的函数,导致t变化时无法读取简单描述一下:RiccatiSolve[...
The singular diffusion equation called total variation (TV) flow plays an important role in image processing and appears to be suitable for reducing oscillations in other types of data. Due to its singularity for zero gradients, numerical discretizations have to be chosen with care. We discuss dif...
