flac常用命令（FLAC common commands）FLAC3D common commands1. What are the first commands you need to master? Answer: commands such as gen, ini, app, PLO, solve, such as modeling, initial conditions, boundary conditions, postprocessing, and solving are required.2. How do I output the post-processing diagram of the model? Answer: File/Print, type/Jpg, file, and then select File/Print, save the format as JPE file.3. How do I call a file? Answer: File/call or call command 4, how to exert surface force? Answer: app nstress 5, how to adjust the size and angle of view? Answer: use x, y, Z, m, Shift keys, and use Ctrl+R, Ctrl+Z and other shortcut keys together. 6, how to carry out boundary constraints? Answer: fix x ran (the constraint is speed, in the initial case, the constraint is equivalent to the displacement constraint). 7, how do you know the ID of each unit? Answer: double-click the surface of the cell with the mouse to know the ID and coordinates of the unit. 8, how to slice? Answer: PLO, set, plane, ori (point coordinates), norm (normal vector), PLO, con, SZ, plane (showing the slice of the stress in the direction of the z) 9, how to save the result of calculation? Answer: save + file name 10, how to call saved results? Answer: rest + file name; or File / Restor 11, how to pause the calculation? Answer: Esc 12, how to pause in the program, and can restore the calculation? Answer: add the pause command to the command and proceed with continue. In our step by step solution, we want to get the result of a certain process, not wait until all the requests are finished, and then we can correct the error when the distribution is wrong, not wait for the result to come out. 13, how do you skip a calculation step? Answer: in the calculation, press the space bar to skip thiscalculation, automatically go to the next 14, Fish what is it? Does Fish have to learn? Answer: it's the built-in language of FLAC3D that can be used to parameterize models and perform commands that cannot be performed by themselves. Fish doesn't have to learn. When you need it, check Mannual and get the variables you need. What is the command file format allowed by 15 and FLAC3D? Answer: does not matter, as long as it is a text file, what suffix can be. 16. How do I call some optional modules? Answer: config dyn (fluid, creep, cppudm) 17, how to impose constraints around the cylinder? You can use fix, ran, cylinder, end1, end2, radius, R1, cylinder, end1, end2, radius, R2, not, R219, about DD, dip dip-direction angle, measured in: the global xy-plane clockwise from the positive y-axis from y to X is the shaft clockwise turn angle; dip dip angle, measured in the negative Z-direction from the global xy-plane this is the angle between the XY plane and Z axis; dip the angle between the reference plane and the XY plane symmetry, symmetry plane and XY angle reference plane is a ray projection in the XY plane; DD refers to the positive direction of axis Y clockwise direction steering angle (clockwise) projection to the normal direction is determined in the XY plane, and then determine the dip. Refers to dip XY from the plane to the plane defined by the angle. 20, range command: 1 spherical range, is a center, part of the different radius between the force applied to the sphere, with the constraint, command, command: range annulus center XYZ radius R1 R2 (Center) (two radius), want to express is spherical, r1r2 value difference can be small, such as the radius 2.9 3.1 when the range is a radius of 3 plane. The order of force is applied to the torus of a cylinder, exerting forceor restraint.范围缸end1 XYZ end2 XYZ半径R（端是表示柱体断面的中心点坐标）范围平面以上表示的是Z大于0的上部结构范围面吹表示的是Z小于0的下部结构范围DD DIP B XYZ表示的是走向角度起源，倾向角度B 的面DD表示，当面与xoy面相交时的垂线与Y轴正向的夹角，顺为正，说白话，就是面的指向方向面是朝那个方向的意思。
