My personal notes on Maya Fluid<\/h2>\n

Hi I’m Morteza Ahmadi<\/p>\n

Today I start thinking about what Fluids Attributes Will\u00a0 do?!<\/p>\n

So 21\/sebtember\/2010 :<\/p>\n

[\/et_pb_text][et_pb_text background_layout=”dark” text_orientation=”left” admin_label=”Solverquality” use_border_color=”off” border_style=”solid” disabled=”off”]<\/p>\n

1.Solver Quality<\/h5>\n

——————-<\/p>\n

I start looking at Fluid’s attributes (and what is this ?!! : FluidSolverQuality!?)<\/p>\n

\u00a0FluidSolverQuality<\/strong>: i change it from 0-1000 and i didn’t see any serious change after value:50 its just slowing down playback speed, and another thing is increasing the number will speed up simulation: It reach Top At:<\/p>\n

 <\/p>\n

Quality: 1—-Frame:55\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Quality: 10—-Frame:51\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Quality: 20—-Frame:49\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Quality: 1000—-Frame:49<\/p>\n

 <\/p>\n

I think its better to leave it at Default Value it has both quality and performance.<\/p>\n

2.HighdetailSolver<\/h5>\n

——————-<\/p>\n

This one is really important, See image below and some Video From “FluidHDS”.<\/p>\n

I think its better to use :\u00a0 off:<\/strong> any soft effect |\u00a0 all except Velocity:<\/strong> For tin and soft smokes that has some cool swirl and details, i am mostly using this one as it has good detail and also a cleaner look compare to “All” | only velocity:<\/strong> i don’t know never find it useful for anything | all: <\/strong>explosions or\u00a0 very detailed and noisy smoke<\/p>\n

[\/et_pb_text][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/HighDetailSolver.jpg” show_in_lightbox=”on” url_new_window=”off” use_overlay=”off” sticky=”off” align=”left” force_fullwidth=”off” always_center_on_mobile=”on” admin_label=”Image” use_border_color=”off” border_color=”#ffffff” border_width=”1px” border_style=”solid” disabled=”off”] [\/et_pb_image][et_pb_text background_layout=”dark” text_orientation=”left” admin_label=”Substep” use_border_color=”off” border_style=”solid” disabled=”off”]<\/p>\n

A Day has passed- yesterday i create a Cool But a very hot Sun. i save the file on C: Drive and because of a viruses i reinstall windows,end of the story, i don’t have the file anymore and i try to recreate it but it just doesn’t look that good<\/p>\n

So i want to Try Attributes to see why i can’t achieve that look and quality anymore<\/p>\n

 <\/p>\n

3.SubSteps<\/h5>\n

——————-<\/p>\n

i can say nothing about this attribute, Maya help says: “Specifies the number of times the solver performs calculations per frame. Substeps are useful for improving the stability and simulation results of fast-moving fluids, fluids with high density grids, and when the High Detail Solve is used”<\/p>\n

then i guess its better to test it on some fast Fluids, take a look at the image below<\/p>\n

[\/et_pb_text][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/Substep.jpg” show_in_lightbox=”off” url_new_window=”off” use_overlay=”off” sticky=”off” align=”left” force_fullwidth=”off” always_center_on_mobile=”on” admin_label=”Image” use_border_color=”off” border_color=”#ffffff” border_width=”1px” border_style=”solid” disabled=”off”] [\/et_pb_image][et_pb_text background_layout=”dark” text_orientation=”left” admin_label=”More test with solve quality and substep” use_border_color=”off” border_style=”solid” disabled=”off”]<\/p>\n

Some more tests with solver quality and Substep<\/p>\n

4.Forward Advection<\/p>\n

——————-<\/p>\n

i think its another way for solving, base on your simulation it some times add more detail and some times reduced it,<\/p>\n

it will look cool for fire<\/p>\n

[\/et_pb_text][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/ForwardAv_2.jpg” show_in_lightbox=”off” url_new_window=”off” use_overlay=”off” sticky=”off” align=”left” force_fullwidth=”off” always_center_on_mobile=”on” admin_label=”Image” use_border_color=”off” border_color=”#ffffff” border_width=”1px” border_style=”solid” disabled=”off”] [\/et_pb_image][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/ForwardAv_1.jpg” show_in_lightbox=”off” url_new_window=”off” use_overlay=”off” sticky=”off” align=”left” force_fullwidth=”off” always_center_on_mobile=”on” admin_label=”Image” use_border_color=”off” border_color=”#ffffff” border_width=”1px” border_style=”solid” disabled=”off”] [\/et_pb_image][et_pb_text background_layout=”dark” text_orientation=”left” admin_label=”Different angle” use_border_color=”off” border_style=”solid” disabled=”off”]<\/p>\n

so i recreated the sun, and i learn that some times you just need to look at your work from different angle<\/p>\n

[\/et_pb_text][et_pb_text background_layout=”dark” text_orientation=”left” admin_label=”Size of fluid” use_border_color=”off” border_style=”solid” disabled=”off”]<\/p>\n

6.Size of the Fluid<\/h5>\n

——————-<\/p>\n

let see what will happen if i resize the Fluid’s container.<\/p>\n

with the autoresize = on<\/p>\n

well. noting happend !?<\/p>\n

[\/et_pb_text][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/fluidsizeAutoResize.jpg” show_in_lightbox=”off” url_new_window=”off” use_overlay=”off” sticky=”off” align=”left” force_fullwidth=”off” always_center_on_mobile=”on” admin_label=”Image” use_border_color=”off” border_color=”#ffffff” border_width=”1px” border_style=”solid” disabled=”off”] [\/et_pb_image][et_pb_text background_layout=”dark” text_orientation=”left” admin_label=”Size Emitter” use_border_color=”off” border_style=”solid” disabled=”off”]<\/p>\n

7.Emitter size & Fluid Resolution<\/h5>\n

——————-<\/p>\n

well. it change many things but\u00a0 I find out that maybe it only changes the resolution. look at the image below “Image 7_1” notice the #4, the auto resize doesn’t work well<\/p>\n

that usually happened at high Fluid resolution values, Look at the image “Image 7_2” there is no change in the size of the emitter i only change the resolution value.<\/p>\n

notice that the value of 600 & 800 are like #4 of the “image7_1” its really bad if there were no way for using auto resize with high Resolution Fluids. How can i Fix it ?<\/p>\n

 <\/p>\n

Thank god, i learned the answer of this Question, earlier today, maybe there be another ways But Mine is using a low density Emitter. look at the image “image7_3”.<\/p>\n

Low density Emitter:(a normal Volume emitter, Density Metod = Replace, Density\/Voxel\/Sec = 0.001, ) i Find out another thing if you set the fluid drop off to 0 it will kill the Fluid’s density and if you set it to higher values then you can use it to lower the density at that point or just as a way to resize the fluid container.<\/p>\n

Note: the depth of the emitter is important too (Z Axis).<\/p>\n
