CFLUX 关键词报错

QustFelix

关于CFLUX的使用，我写了个命令如下：

*Cflux
1, 11, 100.
2, 11, 100.

5024是节点号

程序报错：in keyword *CFLUX, file "Job-1modified.inp", line 4755: Unknown assembly id 1.

in keyword *CFLUX, file "Job-1modified.inp", line 4755: Unknown assembly id 2.

按照文档，第一行数据可以是节点编号也可以是节点组，但是我用节点编号就是报错，不能理解，求解释。

参考文档解释：

Data lines to define a concentrated flux:

First line:

• Node number or node set label.
  
  
  
• Degree of freedom. If a blank or 0 is entered, degree of freedom 11 is assumed. For shell heat transfer elements enter 11, 12, or 13, etc.
  
  
  
• Reference magnitude for flux (units of JT–1 in heat transfer analysis and PL3T–1 in mass diffusion analysis).
  
  
  

Repeat this data line as often as necessary to define concentrated fluxes at different nodes and degrees of freedom.
