求助，ANSYS用间接法进行焊接热应力分析中，SOLID70对应的单元到底是哪个哦？
求助，ANSYS用间接法进行焊接热应力分析中，ETCHG,命令中SOLID70对应的是SOLID45,怎么在运行中转化成了SOLID185来进行运算了呢？？急，请各位大侠出手相救 ansys 10这前版本solide70 etchg,tts后转为solid45,自ansys11 转为solid185,注意ansys帮助中etchg说明的所作的已作改变,市面上教材多数未变过来 看ansys11帮助文件,solid45正被solid185取代Release 11.0 Documentation for ANSYS
Commands Reference | E Commands |
ETCHG, Cnv
Changes element types to their corresponding types.
PREP7: Element Type
MP ME ST PR PRN <> <> FL EM EH <> PP <>
Cnv
Converts the element types to the corresponding type. Valid labels are:
ETI—Explicit to Implicit
ITE—Implicit to Explicit
TTE—Thermal to Explicit
TTS—Thermal to Structural
STT—Structural to Thermal
MTT—Magnetic to Thermal
FTS—Fluid to Structural
ETS—Electrical to Structural
Notes
Changes the currently defined element types to their corresponding types. Elements without a companion element (listed above) are not switched and should be switched with the ET command to an appropriate element type or to a null element. The KEYOPT values for the switched element types are reset to zero or to their default values. You must check these values to see if they are still meaningful. Additionally, if Cnv = ETI, ITE, or TTE, all real constants are set to zero.
If Cnv = ITE, you will need to choose a material model that corresponds to your previously-defined material properties. If working interactively, you will be prompted to do so.
Element types LINK8 and LINK10 lack a third node; however, their corresponding companion explicit element types, LINK160 and LINK167, require a third (orientation) node. If you are using element types LINK8 or LINK10, you must first convert the element type using this command and then manually define the third node of LINK160 or LINK167 elements using EMODIF.
Also, if you are converting BEAM4 to BEAM161, you may need to manually define the third node of BEAM161 elements as well. However, BEAM4 allows you to define a third, optional node. If you have defined this third node on BEAM4, then the conversion to BEAM161 will be completed automatically when you issue this command. If you did not define the third node on BEAM4, then you must manually define it on BEAM161 using EMODIF.

回复 板凳 kglxhxg 的帖子
谢谢，明白了！ 我也是碰到类似问题热分析用的shell132
ETCHG，TTS 命令后
转成了shell182
我用的ansys 11.0帮助里面写的是shell132->shell93啊？
求助
