AQL - AQWA Interface for Excel
Contents
1. REF If a function is used and VALUE is displayed text has probably been entered for an argument which should be a number or vice versa If N A appears one of the arguments has probably been omitted AQL functions are included in formulae just like ordinary Excel functions such as sine sum max etc If you cannot remember the order or meaning of the arguments to the function use Excel s function wizard the AQL functions are listed in a category called AQWA Excel32 A simple example is shown below AQLposition C Alpha adtest01 1 z 100 This function returns the Z displacement at time step 100 for structure number 1 in model adtest01 stored in directory C Alpha To avoid typing such long formulae it is a good idea to use absolute and relative row and column references in Excel as much as possible This is illustrated in the example below where the user requires the displacement of one structure in all six degrees of freedom for every thousand time steps The directory and the model name are entered into cells Al and A2 splitting these up makes changing to a different model easy These items are then concatenated into a single string in cell A3 The number of the structure is entered into cell B4 The six degrees of freedom namely X Y Z RX RY and RZ are entered into cells B5 C5 DS ES FS and G5 The time steps are entered into cells A6 A7 A8 A9 A10 A11 and A12 The full formula for displacement in cell B6 wou2. Excel 1 Overview 1 1 Introduction AQL is an interface from AQWA to Excel It is intended to facilitate the development of Excel spreadsheets that require data from AQWA databases The interface consists of a series of Excel functions that can be accessed within the spreadsheet to recover data directly from the AQWA database A typical example might be an application that tabulates motions of a particular structure and then undertakes a post processing exercise Key features are e Direct access to the AQWA database information using Excel Function calls e Recovery of RAOs using structure number frequency and direction e Recovery of time history results e Error trapping e Simple installation 1 2 Compatibility AQL is available for Excel variants designed to run under Windows 20007 Windows XP or Windows Vista The interface program does not require an AQWA dongle or security file to operate The Microsoft Excel logo is a registered trademark of Microsoft Corporation Windows 2000 is a registered trademark of Microsoft Corporation Windows XP is a registered trademark of Microsoft Corporation Windows Vista is a registered trademark of Microsoft Corporation Contains proprietary and confidential information of ANSYS Inc and its subsidiaries and affiliates 1 1 AQL User Manual Running AQL 2 Installation 2 1 Installing AQL Installation of AQL is straightforward It is assumed that the reader is reasonably famil
