For example, the nstruction"copy filel"means to type the w ord copy, to type a space. and then to type filel Menu/Command Computer type is also used to display the com mands that are needed to perform a specific task Menu levels are separated by forward slashes (/) For example, the instruction hoose File/Open"means to choose the Open command under the file menu Italics Italic type is used for emphasis and for the titles of manuals and other publications. Italic type is also used for key board entries when a name or a variable must be typed in place of the words in italics. For example, the instruc- rion“ copy filename” means to type the word copy, to type a space, and then to type the n amc of a filc. such as filel Keys Helvetica type is used for labeled keys on the computer keyboard. For example, the instruc- tion"Press Return?"means to press the key on the com puter that is lahcled Return www.docin.co Installation Before you use Maxwell 3D, you must 1. Set up your systems graphical windowing systerm 2. Install the Maxwell softw are, using the directions in the Ansell PC or UNIX Installation guide If you have not yet done these steps, refer to the ansoft installetion guides and the documentation that came w ith your computer system or ask your system administrator for help sing a Graphical User Interface If you are familiar with the concepts of using a mouse, menus, and other graphical user interface(GUn)tools, skip to Chapter 1 “ Introduction If you have not used GuI systems before, this section will help you understand some of the terminology used in this guide. Since GUI are basically visual, the best way to learn to use them is by practicing on your system Most gui systcms usc a mouse as a poinTing device, with which you can select areas on the screen for command execution and moving from one program to another. Your mouse may have 2 www.do or 3 buttons; Maxwell 3D ignores the middle button on 3-button dels Ansoft products do not usc this button. You can program mouse buttons to work in non-standard ways, as you might want to if you are left-handed. For simplicity, the left-hand hutton (under your forefinger if you are right-handed) is called the left button, and the one on far right is the right mouse button. You will probably find the terms intuitive once you use these buttons a few times Point and click; Right click To choose an item with the mouse, first move it on your desk until the arrow cursor is on that item; you are now pointing" at the item. Next, ress and release the left bu tton th lled"clicking " Point-and click is the most common action you will make with your mouse ally, click" refers to a lefi se button click You can sometimes use your right mouse button to access or enter commands. In the 3d Modeler for instance, a right mouse button click causes a short menu of commands to appear at the moust cursor. Generally, right click "refers to a right mouse button click Double-Click Occasionally you may want to sclect all of thc text in a box,or perform a special lask(such as indicating the end of drawing a line while you are using Maxwell 3D. You can do this efficiently by quickly clicking twice with your left mouse button -a double Dragging objects; Click and Hold When you are drawing in the 3D Modeler, you can often use your mouse to enter objects and move around the screen. Frequently, you will click the mouse button and hold it down until the next part of the command is reached (the object is oved, the next point is entered and so forth). If you click and hold on the edge of a w indow, you can position, or drag, the window on your screen. You can often drag objects in Maxwell; experiment to see w hat will move Tool Bars Tool bars are shortcut methods for entering commands. There is a tool bar in the 3d Modeler and most of the setup modules for several command s. To use a tool bar. click the mouse cursor on the button you want to use. Here is an example of a tool bar 囗。圖哦良风≌固函 Menus Within each screen of maxwell 3d are areas w hich list subsets or menus,of commands. You can access a menu by clicking your mouse on the word or button that indicates the menu. The menu is pulled down, listing the commands available on that menu. (For example thc New command is availablc on the File mcnu. Usually, thc mcnu will remain displayed until you choose a command, or click on the desktop to exit. If the menu does not remain displayed, click and hold the mouse button, then release the button to make your choice File Edit view New open Close Save ctrl+S Save As Import Export Exit ctrl+Q An arrow on the right side of a command indicates that there is a submenu for that command. An ellipsis (. )indicates that a pop-up window appears aftcr choosing this command When you are asked to use a menu command, each level is separated by a"/". Thus, to zoom in on a drawing, you would choose the view Loom In menu command To open a new file, you would choose File/ There are also pop-up menus, which appear when you righL-click on a maxwell modeler window. choose commands from thcsc menus in the same way as from menu bars For more information on using GUIs, refer to"User Interface"in the Maxwell Control Panel,s online help system Other References For detailed information on Maxwell 3d commands refer to the online documentation for the maxwell 3d field simulator To start maxwell 3d, you must first access the maxwell control Panel. for more detailed inform ation on the maxwell control panel commands, refer to the Maxwell Control Panels online help system www.docin.com Table of Contents 1.
