| Abstract: | The lumped mass nonconforming finite element method for parabolic problem was discussed.Because the usual regularity condition would not necessarily be satisfied for region division,so by using Crouzeix-Raviart-type nonconforming element and Riesz projection,the error estimate could be obtained,so that,the engineering application of the finite element methods would be extended. |
