I have code for defining a single vertical rod, but how would I rotate this rod say 45 degrees towards +x axis?</p> <p>The code for the single rod is:<br /> source_radius = Nx/6;<br /> magnitude = 5;</p> <p>ball_magnitude = 0; % [Pa]</p> <p>ball1_x_pos = Nx/2; % [grid points]<br /> ball1_y_pos = Ny/2; % [grid points]<br /> ball1_z_pos = Nz/2; % [grid points]<br /> ball1_radius = 10; % [grid points]<br /> ball_1 = ball_magnitude*makeBall(Nx, Ny, Nz, ball1_x_pos, ball1_y_pos, ball1_z_pos, ball1_radius);<br /> p0 = ball_1;<br /> p0(round(Nx/2)-1:...<br /> round(Nx/2)+1,round(Ny/2)-1:...<br /> round(Ny/2)+1,round(Nz/2-source_radius):...<br /> round(Nz/2+source_radius) ) = magnitude;</p> <p>Thanks!<br /> Karl </p>
