自定义材料-material check曲线拟合问题

    • jqwei

      背景:自定义一个材料时,material check发现曲线拟合差别较大,其中绿色是实测数据。

      问题:

      1.这个拟合是基于什么样的模型,这个模型可以修改吗?

      2.如何使拟合的偏差变小呢?

      3.这样的偏差实际仿真中会影响很大吗?

      您好,

      1.自定义材料拟合模型是软件自带的,不可修改;

      2.您可通过调整Fit tolerance、Max coefficients及高级设置中的相关参数来使RMS变小,

      具体调整策略可参见如下链接

      3.偏差大小要依据您的拟合曲线与实测值之间的差距而定。
