『求助』谐响应分析时出现错误提示，求高人指点

我做谐响应分析，出现这样的错误提示
no stiffness matrix for element 241 found on the emate file.probably due to missing EMATEWRITE,YES in the first load step

241单元是beam188单元，单元属性中也打开应力应变计算选项的
不知道他的提示中EMATEWRITE选项在哪儿设置，望高人指点！

EMATWRITE, Key

Forces the writing of all the element matrices to File.EMAT.

Key

Write key:

YES	—	Forces the writing of the element matrices to `File.EMAT` even if not normally done.
NO	—	Element matrices are written only if required (default).

Notes

Forces the program to write the File.EMAT and is used if you intend to issue a subsequent PSOLVE that requires File.EMAT as a prerequisite or if you plan to follow the initial load step with a subsequent inertia relief calculation using the IRLF command.

This command is also valid in PREP7.
