ansys初学者命令手册：* BEGINNERS GUIDE TO ANSYS COMMANDS *The symbol * corresponds to the following:* - k, l, a, v, e, n, cm, et, mp, r where =k - Keypointsl - Linesa - Areav - Volumese - Elementsn - Nodescm - componentet - element typemp - material propertyr - real constant$ - d, f, sf, bf, ic, where =d - DOF constraint (ux. in Structural, Temp in thermal,f - Force Load ( Heat in thermal)sf - Surface load on nodesbf - Body Force on NodesMore Commands can be generated by sensible combinations of $* commands. See the following list of $* possible options$* - dk - DOF constraints on KP (Vx,Vy,Pres. in CFD)dl - DOF constraints on Linesda - DOF constraints on Areasfk - Force on Keypointssfl - Surface load on Linessfa - Surface load on Areassfe - Surface load on element facesbfk - Body Force on Keypointsbfl - Body Force on Linesbfa - Body Force on Areabfv - Body Force on Volumesbfe - Body Force on Elementsic - Initial Conditions,p - If ,p was issued at the end of the Command(in Input Win GUI based picking menu will be activated. Useful for listing, plot deleting, etc.*1.

BOOLEAN Operations: IntersectCOMMAND SYNTAX : *IN*AINA,p / VINV,p / LINL,p / AINV,p / LINV,p / LINA,p*9. BOOLEAN Operations: GLUECOMMAND SYNTAX : *GLUEVGLUE,p / AGLUE,p / LGLUE,p*10. Boolean Operations: SUBTRACT/DIVIDE:COMMAND SYNTAX: *sb*,pSee the following examples to understand how this works:asba,p - Subtract Area from Areaasbl,p - Divide Area by linevsba,p - Divide volume by Arealsbw,p - Divide line by Workplanevsbw,p - Divide volume by Workplaneasbw,p - Divide area by Workplanevsbv,p - subtract Volume by another volumeMore combinations exist. The user needs to explore them for themsea part of learning*11. Boolean Operations: Overlap:COMMAND SYNTAX: *OVLAP,pAOVLAP,p / VOVLAP,p*12.

Dragging operationCOMMAND SYNTAX : *drag,pvdrag,p - Drag areas along a line to create a new volumeadrag,p - Drag line along a line to create a new arealdrag,p - Drag KP along a line to create a new line*14. Copy Geomtric entitiesCOMMAND SYNTAX : *GEN,pKGEN,p / LGEN,p / AGEN,p / VGEN,pPlease note that *GEN commands are also used for MOVE operations.lies in the value specified in the 10th field of these *GEN commanit is 0 - which does the COPY operation. If specfied as 1 - itoperation*15. Bottom -to- Top modeling commands:COMMAND SYNTAX : *,p & *,pk,p - Allows user to pick KP in the Workplanel,p - Create lines from existing KPak,p - Create area from KPal,p - Create area from linesv,p - Create Volume from KPva,p - Create Volume from Arease,p - Create Elem from existing nodesen,p - Create Elem from nodes*16. To apply common Boundary Conditions such as DOF constraint, FoLoads, Bodyforce Loads and Initial conditions* - is meant for the KLAVE entities only (KLAVEN stands for KP,Volumes & ELem )16a. DOF constraint :COMMAND SYNTAX : $*,p ( Please Note: NOT all * are valid)See the valid combinations below:D,p - To apply DOF on nodesDK,p - To apply DOF on KeypointsDL,p - Apply DOF on LinesDA,p - Apply DOF on Areas ( symmetry or Anti-symmetry will be pr*16b. FORCE Loading:COMMAND SYNTAX : $*,pSee the valid combinations below:f,p - Forces on nodesfk,p - Force on Keypoints(fa,p or FV,p or FL,p - Since force cannot be applied on Linesvolumes. this command does not exist.)*16c. Surface Loads:COMMAND SYNTAX : $*,pSee the valid combinations below:sf,p - Surface Load on a set of Nodessfl,p - Surface Load on Linessfa,p - Surface Load on Areasfe,p - Surface Load on Element(SFk,p and SFV,p do not exist since pressure cannot be applied onand neither can it be applied on a volume)*16d.
