This study aimed to solve the three-dimensional differential equations that treat natural phenomena as the spread of a substance or the movement of fluids. The three-dimensional fluid motion equations were determined in differential equations and solved numerically by the method of the specified differences, and to find an approximate solution using the Tyler expansion to find the value of the derivative at each point in the field to predict this movement and the use of the BISC language in finding the results of solving these differential equations. replica omega
