User subroutine?SDVINI:??

1.用戶子程序 SDVINI ：

will be called for user-subroutine-defined initial solution-dependent state variable fields at particular material points, shell section points, contact secondary nodes, or for user elements (see?Initial Conditions);
?用戶子程序定義的初始解相關(guān)狀態(tài)變量場(chǎng)將被調(diào)用，以便在特定材料點(diǎn)、殼體截面點(diǎn)、接觸次要節(jié)點(diǎn)或用戶單元上進(jìn)行計(jì)算（請(qǐng)參見(jiàn)“初始條件”）。

2.can be used to initialize solution-dependent state variables allocated as described in?Allocating Space for Solution-Dependent State Variables; and
可用于初始化如Allocating Space for Solution-Dependent State Variables

中所述分配的解相關(guān)狀態(tài)變量；和

3.returns a value of zero for any solution-dependent state variables that have no defined initial condition.
對(duì)于任何沒(méi)有定義初始條件的解相關(guān)的狀態(tài)變量，返回零值。

Variables to Be Defined?要定義的變量

STATEV(1)

First solution-dependent state variable.
第一個(gè)解相關(guān)的狀態(tài)變量。

STATEV(2)

Second solution-dependent state variable.
第二個(gè)解相關(guān)的狀態(tài)變量。

STATEV(3)

Third solution-dependent state variable.
第三個(gè)解相關(guān)的狀態(tài)變量。

Etc.

Only?NSTATV?solution-dependent state variable values should be defined.
只應(yīng)定義 NSTATV 解相關(guān)的狀態(tài)變量值。

Variables Passed in for Information
傳遞信息的變量

COORDS

An array containing the initial coordinates of this point. Coordinates are not available for user elements.
包含該點(diǎn)初始坐標(biāo)的數(shù)組。坐標(biāo)不可用于用戶單元。

NSTATV

User-defined number of solution-dependent state variables (see?Allocating Space for Solution-Dependent State Variables).
用戶定義的解相關(guān)的狀態(tài)變量的數(shù)量（請(qǐng)參閱為解相關(guān)的狀態(tài)變量分配空間）。

NCRDS

Number of coordinates. This value is zero for user elements.
坐標(biāo)數(shù)。對(duì)于用戶單元，此值為零。

NOEL

Element number.??單元編號(hào)

NPT

Integration point number in the element (not relevant for user elements).
單元中的積分點(diǎn)編號(hào)（與用戶單元無(wú)關(guān)）。

LAYER

Layer number (for composite shells and layered solids).
層數(shù)（對(duì)于復(fù)合殼和分層實(shí)體）。

KSPT

Section point number within the current layer or section. Section point 1 is used for all pure heat transfer, coupled temperature-displacement, and coupled thermal-electrical-structural analyses.
當(dāng)前層或截面中的截面點(diǎn)編號(hào)。截面點(diǎn) 1 用于所有純熱傳遞、溫度-位移耦合和熱-電-結(jié)構(gòu)耦合分析。
