小弟刚入门，做了一个离合器一对摩擦片摩滑过程的热机耦合分析，提交作业时出现如下错误：

Degree of freedom 11 and at least one of degrees of freedom 1 thru 6 must be active in the model for *coupled temp-disp. Check the procedure and element types used in this model.
Invalid load type on element 21 instance fricdisk-1. Load type f is not valid for element type c3d8r
......
Invalid load type on element 109 instance fricdisk-1. Load type f is not valid for element type c3d8r
Error message limit reached. No further error messages will be reported.
Please see the dat file for more errors.
Analysis Input File Processor exited with an error.

请问该如何解决？
多谢！

按照英文内容更改就行了

问题已解决。出现新问题。求解释以下错误和警告，多谢!

Error:"The independent variables must be arranged in ascending order"

Warnings:"The option *boundary,type=displacement has been used; check status file between steps for warnings on any jumps prescribed across the steps in displacement values of translational dof. For rotational dof make sure that there are no such jumps. All jumps in displacements across steps are ignored"
