Now that 300 hours becomes 15 hours on the laptop, which is tolerable. If you do both those things, the solution will take 1/20 of the time to compute. If you can increase the minimum length by a factor of 4, the solution will compute in 1/4 of the time. Look at the Mesh Metric called Characteristic Length. For example, if you multiply the density by a factor of 25, the solution will take 1/5 of the time to compute the solution.Īnother change is to increase the minimum element size. You can edit the density of the material to artificially reduce the time it takes to solve. Here are some changes you can make to your Explicit Dynamics model to make it solve in less time. then the model will take only 30 hours on the laptop computer. What you need to do is make changes to the model to increase the time step from 1e-7 to 1e-6. What is the clock speed of your laptop? You will find the lab computer clock speed is not going to be much faster than your laptop (it may even be slower), it is certainly unlikely to be twice as fast and even if it was, that is still 150 hours of solution time, which is intolerable. For example, if the solver estimates that it will take 300 hours on your laptop because the time step is 1e-7 seconds, that same time step will be present on the lab computer. You have to build the model from scratch, sorry.Īre you using Explicit Dynamics? That calculates a time step that can be tiny and result in long solution times. Unfortunately, there is no easy way to save a project to an earlier version.
