Animating post views

Use the Animation command to generate and control the display of animation frames. You can animate:

• A single result from zero to its maximum value.

• Mode shapes through their full range of motion.

• A single result across multiple time steps.

• Optimization variables across multiple iterations.

• Flow along streamlines.

• Simcenter 3D Multiphysics axisymmetric and cyclic symmetry.

• Waves results from Simcenter 3D Multiphysics cyclic symmetry harmonic indexes.

When working in multiple viewports, you can animate multiple post views simultaneously. Hold Ctrl and click in the Post Processing Navigator to select multiple post views to animate.

Streamline animations

When you animate steady-state velocity streamlines, the software releases a pulse on each streamline in the display. This pulse moves along on the streamline in the direction of the velocity vector, and the speed of a pulse derives from the velocity at each location along the streamline.

The software represents pulses visually using a bubble display. The size and color of the bubbles are determined by the last-specified settings on the Result dialog box.

The total time period of the animation begins when the first bubble of a pulse appears, and ends when the last bubble disappears from the display. You can release a single pulse, or continuous pulses at a fixed time interval.

• When Continuous release is cleared, one pulse is released on each streamline. At the end of the time period, one full animation cycle completes and the animation repeats from the beginning.

• When Continuous release is selected, pulses are released throughout the animation cycle at fixed time intervals. You specify the duration of the animation cycle as a multiple of the time period.

You can control the synchronization of pulses; that is, you can specify that pulses arrive at certain locations on all streamlines at the same time. For example, you can specify that all bubbles in a single pulse arrive at the streamline seed points at the same time.

Transient velocity streamline displays are animated like any other transient result. For each time step, the software regenerates the streamline shape, and the plotted contour results and streamline style are updated.

Forward and backward wave animations

For cyclic symmetric harmonic results with all sectors displayed, use the Animate command to perform forward and backward wave animations. In a wave animation, the number of frames is fixed to the number of sectors.

The following video show a wave animation that starts forward and then transitions backward.

Animating marker plots

When you animate marker plots, the color of the markers reflects the changes to result values. When animating across iterations, you can also set the size of the markers to be static or to be scaled proportional to the result values across the iterations.

When you set the marker size to be scaled proportional to result values across iterations, the animation applies a scaling factor to the marker of the current maximum result value relative to the first maximum non-zero result value. For example if there are 10 iterations in a result (Iter1 to Iter10), and the maximum result values for each iterations are max1, max2, max3, … max10, the scaling factor applied to the size of marker for the nth iteration is:

size_factorn = maxn/max1;

To set the marker size to be scaled in proportional to result values across iterations, use the change size check box in the Animation dialog box. The check box name changes depending on the type of marker. The following shows an animation across three iterations with the Change size of spheres with iterations check box selected.

Saving animation frames in memory

You can use the Save Frames in Memory check box in the Animation dialog box to choose to save frames in memory or load each frame during the animation. Selecting to not save frames in memory can be helpful when the results contain many steps and saving all the frames would require too much memory resource.

• If you select the Save Frames in Memory check box, the animations are smoother after the first cycle especially when an animation requires a considerable time to load each frame. Saving frames in memory requires memory.

• If you clear the Save Frames in Memory check box, the performance of each frame of an animation is based on the time required to load each frame. However, editing and deleting the animation are faster.

Animating deformations without animating color

You can choose to animate color, deformations, or both using the Animate Color and Animate Deformation check boxes in the Animation dialog box. For example, you can select to animate deformations and keep the colors constant throughout the animation. The following shows animating color, then deformation, and finally both.

If you select to animate color, the animation uses the colors in the post view. For an in-phase Acoustic animation, the color is the color of the amplitude.

Animating either color or deformations is only available when animating single results and when you turn on the display of deformations.

Animating the birth and death state of elements

Animations across iterations display the state of elements that are added or removed from a solution at specified times or subcases. The colors reflect the state (active or dead) of the elements for the particular dataset. Elements that are dead are hidden.

Playing animations

You can control the animations through the Animation dialog box, which lets you set the type of animation and display options, such as control the frames. You can also control the animation using the following:

• The Play Animation and Stop Animation commands that appear when you right-click a post view.

• The animation controls in the Animation group of the Results tab. The animation controls let you step through the results and play, pause, and stop the animation.The animation controls in the Animation group of the Home tab. The animation controls let you step through the results and play, pause, and stop the animation.
