6、部程序 Run external programs (spawn a process) during the MSC.Nastran execution,7,兩類DMAP指令Two Types of DMAP INSTRUCTIONS,語句進(jìn)行參數(shù)操作或求解控制（類似于Fortran的一行） Statements - perform parameter operations or solution control (similar to a single line of FORTRAN） 例子: if(A5)B=C+3 $ 模塊對(duì)矩陣或表格操作（與Fortran中，用Call調(diào)用的子程序類似）

7、 Modules - perform operations on matrices or tables (similar to a subroutine call in FORTRAN) 例子: MPYAD A,B,/C $進(jìn)行矩陣計(jì)算C=AB,8,DMAP指令格式Format of DMAP Instructions,所有DMAP指令是自由格式 All DMAP instructions are free-format 位于1-72列 they may use columns 1-72 不必從第一列開始they do not need to start in column 1 以$為結(jié)束標(biāo)志

8、they end with a dollar sign $ 如需要，可以使用多行，但應(yīng)以“/”,“,”或不平衡的圓括號(hào)為續(xù)行標(biāo)志 If needed they may be more than one line long If so, the line must end with a slash (/) or comma (,) or must have unbalanced parentheses 例子: MESSAGE /this is a sample of a dmap statement/ which spans more than one line $,9,帶參數(shù)、表格，矩陣的DM

9、AP指令DMAP Instructions Work With Parameters, Tables, and Matrices,命名約定Naming convention 名稱由1-8個(gè)字符組成，字符A-Z,0-9可用 names are alphanumeric using from 1 to 8 characters, the characters A-Z and 0-9 may be used 以字符A-Z開頭names must start with a letter A-Z 合法的命名: AMATRIX TEST1 合法的命名： 1TIME ALONGNAME TERM3,1,10

10、,參數(shù)Parameters,參數(shù)用于Parameters are used for: 計(jì)算calculations A = B + 3. $ 程序控制program control IF(A3.)THEN $ 模塊間傳遞信息passing information between modules PARAML CASES/DTI/1/149/S,N,SDAMP $ (從表格CASES的第1記錄的第149字提取值保存在參數(shù)SDMAP中，并且不能通過情況控制卡改變） 識(shí)別qualifiers 用于識(shí)別數(shù)據(jù)庫中的信息（ SEID, PEID, MPC, SPC等）used to identify in

11、formation stored in the database (SEID, PEID, MPC, SPC, etc),11,參數(shù)（續(xù)）Parameters (Cont),參數(shù)是取單值的可變量Parameters are variables with a single value 有效參數(shù)類型如下Allowable Types of Parameter are as follows: 整型Integer ，(I) - 1 單精度實(shí)型Real-single precision ，(RS) - 1.23 雙精度實(shí)型Real-double precision (RD) - 1.23D-01 單精度

12、復(fù)型Complex-single precision， (CS) - (1.0,.12)= 1. + .12i 雙精度復(fù)型Complex-double precision(CD) - (1.3d3,1.23D04) 字符型Character ，(Chari) 其中，i為字符數(shù)where i is the number of characters - MY NAME (CHAR7) 邏輯型Logical ，(LOGICAL) - TRUE,12,矩陣與表格Matrices and Tables,MSC.Nastran中使用的信息為矩陣或表格形式Information used in MSC.Na

13、stran is in the form of either matrices or tables 從輸入文件得到的信息轉(zhuǎn)化為表格Information from your input file is converted into tables 這些表格用于產(chǎn)生質(zhì)量、剛度、阻尼、載荷矩陣 These tables are used to generate mass, stiffness, damping, and loading matrices 程序調(diào)用這些矩陣求解問題These matrices are used by the program to solve the problem,13

14、,矩陣與表格（續(xù)）Matrices and Tables（cont.),求解結(jié)束后，用矩陣建立表格，將表格打印輸出、繪圖、或?qū)懭胛募楹筇幚沓绦蚴褂?Once the solution is known, the matrices are used to create tables which will be printed, plotted, and/or written into a file for a post-processing program to use 所有矩陣和表格由DMAP模塊建立 All matrices and tables are created by DMAP m

15、odules 矩陣和表格不能用于輸入，除非他們是前一模塊的輸出They may not be used as input unless they have been already used as output from a previous module 一條重要定理是：輸出輛次。通常，一個(gè)矩陣或表格用于輸出僅一次。如果要在一個(gè)DMAP模塊中試圖建立一個(gè)已經(jīng)建立好的矩陣，將出現(xiàn)致“FATAL”信息。An important rule is “output-twice” in general, a matrix or table may be used as output only one t

16、ime. If a DMAP module attempts to create a matrix which has already been created, a FATAL message will occur,14,矩陣與表格（續(xù)）Matrices and Tables（cont.),所有矩陣和表格都可作為“輸出” All matrices and tables are available for “output” 標(biāo)準(zhǔn)輸出（應(yīng)力、位移等）Some are standard output (stresses, displacements, etc) 僅內(nèi)部使用（如矩陣）Some are

17、 used internally only (matrices) 輸出進(jìn)行后處理（幾何、單元特性，材料等） Some are written out for Post-processors (geometry, element properties, materials, etc) 矩陣采用標(biāo)準(zhǔn)格式 Matrices follow a standard format 表格有許多不同的可能形式 Tables have many different formats possible 參考DMAP模塊目錄或NDDL表，查詢標(biāo)準(zhǔn)表格式 See the DMAP Module Dictionary or

18、 a listing of the NDDL to see the format of the standard tables,15,DMAP模塊格式DMAP Module Format,調(diào)用DMAP模塊的標(biāo)準(zhǔn)格式如下 The standard form for the call to a DMAP module uses the following format: module_name input_list/output_list/ param1/param2/param3.$ input_list =輸入表格與矩陣，用“，”分開 list of input tables and matr

19、ices - separated by commas output_list =輸出表格與矩陣，用“，”分開 list of output tables and matrices - separated by commas parami = 該模塊的輸入、輸出參數(shù) parameters used as input and/or output by the module 如果一個(gè)參數(shù)從該模塊輸出，應(yīng)在其前加上“S,N,” or “S,Y” ； 一個(gè)例外是：如模塊中第一次出現(xiàn)該參數(shù)，這時(shí)應(yīng)在DMAP語句處給該參數(shù)一缺損值If a parameter is to be output from the

20、 module it must be preceded by “S,N,” or “S,Y” (the only exception to this rule is if the module is the first occurrence of the parameter, in which case the parameter is given the default value for that location on the DMAP statement),Notice the slashes,16,DMAP模塊（續(xù)）DMAP Modules (Cont),例子: ADD A1,B23

21、/C123/param1/param2 $ 該模塊以矩陣A1、B23為輸入，矩陣C123為輸出，param1、param2為模塊輸入?yún)?shù) this module uses matrices A1 and B23 as input, produces matrix C123 as output. Parameters param1 and param2 are used as input to the module,17,如何使用DMAPHow Do I Use DMAP?,所有DMAP指令位于NASTRAN輸入文件執(zhí)行控制段 All DMAP is done in the executive

22、control section of the input file 可以修改任何已有的SOLs或建立自己的SolutionYou may either modify the any of the existing SOLs or create your own solution 修改已有的SOL,使用ALTERs To modify an existing solution, use “alters” (described later) 建立自己的Solution ,用“MAIN” subDMAPcreate your own solution, create your own “MAIN”

23、subDMAP,18,DMAP Solution一般格式General Form of a DMAP Solution,MSC.Nastran中的每個(gè)Solution 由一個(gè)MAIN subDMAP 和若干個(gè)可能的called subDMAPs Each Solution in MSC.Nastran consists of a MAIN subDMAP and (possibly) a number of called subDMAPs subDMAP與Fortran中子程序類似 A subDMAP is very similar to a FORTRAN subroutine 是DMAP指

24、令的集合 It is an assembly of DMAP instructions with a purpose 可以被其他subDMAPs調(diào)用It may be called from other subDMAPs 本身可以是一個(gè)完整的Solution It may be a complete solution by itself 可以作為其它Solution的一部分 It may be used as a part of many solutions,19,MAIN subDMAP 格式Form of a MAIN subDMAP,MAIN subDMAP 必須用subDMAP語句開始

25、，最后一行必須為“END”語句 A MAIN subDMAP must start with a SUBDMAP statement and the final line must be an END statement 上述兩語句間，包含一系列DMAP指令形成了一個(gè)Solution In between these statements, a series of DMAP instructions are combined to create a solution,20,SUBDMAP語句格式The Form of the SUBDMAP Statement for a MAIN subDM

27、ate a Solution,建立一個(gè)MAIN subDMAP Create a MAIN subDMAP 使用COMPILE語句編譯 use a “COMPILE” statement to compile it COMPILE 語句格式 Format of the COMPILE statement (simplified) COMPILE name, (LIST), (DECK), (REF) name = subDMAP 名稱subDMAP name LIST = 在“.f06”文件中給出清單（可選）provide a listing in the “.f06” file (optio

29、rol section 格式: SOL name(, noexe) name = MAIN subDMAP 名稱或數(shù)字（只有MSC.Nastran本身提供的Solution才能用數(shù)字）MAIN subDMAP name or number (numbers are allowed only for MSC-provided solutions) noexe =隸屬該Solution,但不執(zhí)行 (可選） to attach the solution, but not run it (optional - can be helpful when creating a solution, allow

34、e (in this case, the parameter will assume the default value provided by the module) 參數(shù)由“TYPE”語句定義Parameters are defined by using a “TYPE” statement,27,定義參數(shù)的“TYPE”語句格式Format of the “TYPE” statement when defining Parameters,TYPE PARM,(nddl),(type),(y/n),param1(=default), param2(=default),. 其中: nddl 表
