1、1.ANSYS同 fortran相类似的函数ABS(x) Absolute value of x. SIGN(x,y) Absolute value of x with sign of y. y=0 results in positive sign. EXP(x) Exponential of x (ex). LOG(x) Natural log of x (ln (x). LOG10(x) Common log of x (log10(x). SQRT(x) Square root of x. NINT(x) Nearest integer to x. MOD(x,y) Remainder

2、of x/y, computed as x - (INT(x/y) * y). y=0 returns zero (0). RAND(x,y) Random number (uniform distribution) in the range x to y (x = lower bound, y = upper bound). GDIS(x,y) Random sample of a Gaussian (normal) distribution with mean x and standard deviation y. SIN(x), COS(x), TAN(x) Sine, Cosine,

3、and Tangent of x. x is in radians by default, but can be changed to degrees with *AFUN . SINH(x), COSH(x), TANH(x) Hyperbolic sine, Hyperbolic cosine, and Hyperbolic tangent of x. ASIN(x), ACOS(x), ATAN(x) Arcsine, Arccosine, and Arctangent of x. x must be between -1.0 and +1.0 for ASIN and ACOS. Ou

4、tput is in radians by default, but can be changed to degrees with *AFUN . Range of output is -pi/2 to +pi/2 for ASIN and ATAN, and 0 to pi for ACOS. ATAN2(y,x) Arctangent of y/x with the sign of each component considered. Output is in radians by default, but can be changed to degrees with *AFUN . Ra

5、nge of output is -pi to +pi. VALCHR (CPARM Numerical value of CPARM (if CPARM is non-numeric, returns 0.0). CHRVAL (PARM) Character value of numerical parameter PARM. Number of decimal places depends on magnitude. UPCASE CPARM Upper case equivalent of CPARM. LWCASE (CPARM) Lower case equivalent of C

ANSYS中控制函数APDL Command Action It Takes Usage Tips *DODefines the start of a do loop. The commands following the *DOcommand execute (up to the *ENDDOcommand) repeatedly until some loop

7、 control is satisfied. You can also control looping via the *IF command. ANSYS allows up to 20 levels of nested “do” loops, although “do” loops that include /INPUT, *USE , or an “unknown ” command macro support fewer nesting levels because they do internal file switching. *DO , *ENDDO , *CYCLE , and

8、 *EXIT commands in a “do” loop must all read from the same file or the keyboard. Do not include picking operations in a “do” loop.Be careful if you include a /CLEAR command within a do-loop. The /CLEAR command does not clear the do-loop stack, but it does clear all parameters including the loop para

9、meter in the *DOstatement itself. You can avoid the problem of having an undefined looping value by issuing a PARSAV command before the /CLEAR command, and then following the /CLEARcommand with a PARREScommand. *ENDDO Ends a do loop and starts the looping action. You must use one *ENDDO command for

10、each nested do loop. The *ENDDOand *DOcommands for a loop must be on the same file. *CYCLE When executing a do loop, ANSYS bypasses all commands between the You can use the cycle option conditionally (via the *IFcommand).

The command following the *ENDDOcommand executes next. The *E

12、XITand *DOcommands for a loop must be on the same file. You can use the exit option conditionally (via the *IF command). *IFCauses commands to be read conditionally. You can have up to 10 nested levels of *IF blocks. You cannot jump into, out of, or within a do loop or an if-then-else construct to a

13、 :label line, and jumping to a :label line is not allowed with keyboard entry. You can issue a /CLEARcommand within an if-then-else construct. The /CLEAR command does not clear the *IF stack and the number of *IF levels is retained. An *ENDIF is necessary to close any branching logic. The /CLEAR com

14、mand deletes all parameters, including any that are used in your branching commands. You can avoid any problems that might arise from the deletion of parameters by issuing a PARSAV command before the /CLEAR command, and then following the /CLEARcommand with a PARRES command. *ENDIFTerminates an if-t

15、hen-else construct. (See the *IF discussion for details.) The *IF and *ENDIF commands must appear in the same file. 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 3 页，共 4 页 - - - - - - - - - *ELSECreates a final, optional block separator within an if-then-else constr

16、uct. (See the *IF discussion for details.) The *ELSE and *IF commands must appear in the same file. *ELSEIF Creates an optional, intermediate block separator within an if-then-else construct. If Oper = EQ or NE, VAL1 and VAL2 can also be character strings (enclosed in quotes) or parameters. The *IFand *ELSEIF commands must be on the same file. 3.
